16bfe3b41c raspberrypi: RTC: Ensure a time is set 
Until a time is set, the RTC is not running, and rtc_get_datetime()
returns false without assigning to the out-parameter.

In CircuitPython, this would manifest as arbitrary values being returned,
since uninitialized storage on the stack was being converted into a timestamp.

c95def0b32 raspberrypi: Enable mp3 playback 
The rp2040 is _very_ marginal for mp3 playback, and currently sometimes triggers a bug that gives garbled audio output.  However, it does work for some limited situations.

2ae1e7de61 WIPrp2040: Implement IncrementalEncoder 
Any two consecutive pins can be used for an IncrementalEncoder

Testing performed: Put a synthesized (few hundred counts per second) quadrature signal into GP2/3 and read the encoder out.  Performed filesystem operations at the same time to stress test it.

The reasons for not using common_hal_rp2pio_statemachine_readinto are commented on.

bd01d31542 rp2pio: Add pins_are_sequential 
This can be used where the standard API calls for a list of pins, to check that they satisfy the requirements of the rp2pio state machine, e.g.,
```python
    def __init__(self, pin_a, pin_b):
        if not rp2pio.pins_are_sequential([pin_a, pin_b]):
            raise ValueError("Pins must be sequential")

I named the property `in_available` because it is similar to pyserial.
However, it indicates the number of words in the fifo, not the number
of bytes.

f560b5f3a3 raspberry: switch pico back to the boot2 for W25Q16 
Presumably, switching it to generic hurt performance a bit.

I verified that the build-raspberry_pi_pico/boot2_padded_checksummed.S
built file has the same checksum as the old
bs2_default_padded_checksummed.S

5a00862b1d raspberrypi: allow directly specifying the original boot .S file 
.. all the necessary steps to transform it into a padded, checksummed
file are now done by the build system.

Since it is assigned by "?=", it _should_ be the case that individual
builds can override it.

I did not "test" this per se, but it gives the same content and checksum
(except for the identifying comment with a path) as #4302.

A few minor fixes for corner cases 
* Always clear the peripheral interrupt so we don't hang when full
* Store the ringbuf in the object so it gets collected when we're alive
* Make UART objects have a finaliser so they are deinit when their
  memory is freed
* Copy bytes into the ringbuf from the FIFO after we read to ensure
  the interrupt is enabled ASAP
* Copy bytes into the ringbuf from the FIFO before measuring our
  rx available because the interrupt is based on a threshold (not
  > 0). For example, a single byte won't trigger an interrupt.

Implement audiobusio and enhance PIO for it 
This adds I2SOut and PDMIn support via PIO.

StateMachines can now:
 * read and read while writing
 * transfer in 1, 2 or 4 byte increments
 * init pins based on expected defaults automatically
 * be stopped and restarted
 * rxfifo can be cleared and rxstalls detected (good for tracking when
   the reading code isn't keeping up)
