33dcdd7c03 Updates to enable working SPI TFT 
The backlight enable is active low on our board so the driver doesn't like it.
Toggling to GPIO manually for now.

As fixed the improper SPI bus pins definitions and it works!

a484a93b29 nRF: disk_read must be 4-byte aligned 
.. a requirement that oofatfs needs to be taught to respect.

This problem can be demonstrated with the following snippet, except
that the related file ("test.bin") must also be contiguous on the
filesystem.  You can ensure this by reformatting your device's filesystem
before testing, then copying any single file bigger than 4kB to test.bin.

    f = open("test.bin", "rb")
    f.seek(2048)
    b = bytearray(2048)
    v = memoryview(b)
    f.readinto(v[909:])

13620cc4db nRF: PWMAudioOut: fix half-speed playback of stereo samples 
The "spacing" of "buffer structure" is confusing, use the "channel count"
instead.

Testing performed on nrf52840 feather:

Play stereo and mono, 8- and 16-bit, 8kHz RawSamples representing 333.33Hz
square waves.

Use both mono and stereo PWMAudioOut instances.

Scope the RC-filtered signal and use the scope's frequency
measurement function, verify the frequency is 333 or 334Hz in all tested
cases.

In the "stereo output" cases, verify both the L and R channels.  Verify
the output amplitude is the same in both channels.

In the "stereo output" cases, run a second test where the L channel's
amplitude is attenuated 50%. Verify the output amplitude is correct
in each channel.

47a6eaa297 nrf: i2sout: Assign SWIDTH 
The sample width register was never set, so all samples were played
as though they were 16 bit.

After this change, 8-bit samples no longer produce audio on the MAX 98357A
BOB, because only 16-, 24-, and 32-bit samples are supported by the
hardware.  This will be addressed by a future change to pad samples to
16 bits; see #2323 and the 98357A datasheet page 6.

but in fact it seems that "true" must be passed or else the returned

 * When an odd number of samples were present, the copy continued beyond
   the end of the buffers and caused a hard fault

aabb56c840 nrf: i2sout: Only update hold_value when appropriate 
If we put no samples into the buffer, then there is no last

Detect this condition, and leave the prior value in place.

7f744a2369 Supervisor: move most of systick to the supervisor 
This code is shared by most parts, except where not all the #ifdefs
inside the tick function were present in all ports.  This mostly would
have broken gamepad tick support on non-samd ports.

The "ms32" and "ms64" variants of the tick functions are introduced
because there is no 64-bit atomic read.  Disabling interrupts avoids
a low probability bug where milliseconds could be off by ~49.5 days
once every ~49.5 days (2^32 ms).

Avoiding disabling interrupts when only the low 32 bits are needed is a minor
optimization.

Testing performed: on metro m4 express, USB still works and
time.monotonic_ns() still counts up

2bdccf03a7 cpb: define the SPEAKER_ENABLE_PIN 
This allows the board to disable the onboard speaker until explicitly
enabled in user code.

Testing performed on a CPB:
 * Touching the AUDIO pin with a fingertip no longer generates noise/buzz
 * Generating a waveform with `simpleio.tone` produces no sound by default
 * When the board.SPEAKER_ENABLE is configured as a digital output and
   set True, `simpleio.tone` does produce sound

Note that while guides should include information about SPEAKER_ENABLE, it's
possible that some users who omitted it could view this as a breaking change.
They can fix it by simply adding code similar to

    speaker_enable = digitalio.DigitalInOut(board.SPEAKER_ENABLE)
    speaker_enable.direction = digitalio.Direction.OUTPUT
    speaker_enable.value = True

before using the internal speaker.

Refine _bleio 
This PR refines the _bleio API. It was originally motivated by
the addition of a new CircuitPython service that enables reading
and modifying files on the device. Moving the BLE lifecycle outside
of the VM motivated a number of changes to remove heap allocations
in some APIs.

It also motivated unifying connection initiation to the Adapter class
rather than the Central and Peripheral classes which have been removed.
Adapter now handles the GAP portion of BLE including advertising, which
has moved but is largely unchanged, and scanning, which has been enhanced
to return an iterator of filtered results.

Once a connection is created (either by us (aka Central) or a remote
device (aka Peripheral)) it is represented by a new Connection class.
This class knows the current connection state and can discover and
instantiate remote Services along with their Characteristics and
Descriptors.

d39c85e3f5 nRF: Change analog reference to VCC(/4) 
@ladyada says:
"having this be adjustable (reference) would be ideal cause you can get
absolute voltages but for now, VCC/4 + 4x matches every other chip :)"

... and indeed doing it this way happens to give a much more steady
reading when using a VCC-referenced resistance, and so many of the simple
things you'd wire up are actually VCC-referenced anyway.

f38ee42874 nrf: Add i2s audio output 
Testing performed: I used a Particle Xenon with a HDA1334 I2S DAC.
I played a variety of mono 16-bit samples at 11025 and 22050Hz nominal
bit rates.  With this setup, all the 11025Hz samples sound good.
I tested play, pause,  and loop functionality.

During some runs with 22050Hz samples, there were glitches.  However,
these may have only occurred during runs where I had set breakpoints
and watchpoints in gdb.

I also tested with a MAX98357A I2S amplifier.  On this device, everything
sounded "scratchy".  I was powering it from 5V and the 5V rail seemed
steady, so I don't have an explanation for this.  However, I haven't
tried it with a SAMD board.

77bc1ba03e nrf: PWMAudioOut: Remove the need to wait in "pause" 
The original formulation was because I saw the need to avoid a transition
from playing to stopped exactly when a resume was taking place.  However,
@tannewt was concerned about this pause causing trouble, because it could
be relatively lengthy (several ms even in a typical case).

After reflection, I've convinced myself that updating the registers
in this order in resume avoids a window where a "stopped" event can
be missed as long as the shortcut is updated first.

Testing re-performed: pause/resume testing of looped RawSample and
WaveFile audio sources.

4bae29b925 nrf: enable link-time optimization 
Testing performed: installed freshly built .uf2 on a Particle Xenon.
Checked that circuitpython still starts.
Checked that the size of all .uf2 files for nrf builds are plausible.

Aside from memory savings, the performance of Python code (pystone)
increased by about +14%.

However, this adds about 12-16 seconds to each nrf build.

a183425e00 ports/nrf: Implement audioio.AudioOut using PWM 
This implements AudioOut, with known caveats:
 * pause/resume are not yet implemented (this is just a bug)
 * at best, the sample fidelity is 8 bits (this is a hardware limitation)

Testing performed:

My test system is a Particle Xenon with a PAM8302 op-amp
https://www.adafruit.com/product/2130 and 8-ohm speaker.  There's no
analog filtering between the Xenon's PWM pin and the "A+" input of
the amplifier; the "A-" pin is disconnected.  It is powered from
VUSB.

I used pin D4, which is *NOT* listed as a low-speed-only pin, but
the code does NOT switch the pin to high drive.  This is related to
an open issue for general inability to set drive level for pins
being used by a "special function" on nrf:
https://github.com/adafruit/circuitpython/issues/1270

Nothing about the code I've written should limit the usable pins.

All samples I played were 16-bit, generally monophonic at 11025Hz
and 22050Hz from the Debian LibreOffice package.
