Add `board_deinit` for use with sleep
This changes lots of files to unify `board.h` across ports. It adds
`board_deinit` when CIRCUITPY_ALARM is set. `main.c` uses it to
deinit the board before deep sleeping (even when pretending.)

Deep sleep is now a two step process for the port. First, the
port should prepare to deep sleep based on the given alarms. It
should set alarms for both deep and pretend sleep. In particular,
the pretend versions should be set immediately so that we don't
miss an alarm as we shutdown. These alarms should also wake from
`port_idle_until_interrupt` which is used when pretending to deep
sleep.

Second, when real deep sleeping, `alarm_enter_deep_sleep` is called.
The port should set any alarms it didn't during prepare based on
data it saved internally during prepare.

ESP32-S2 sleep is a bit reorganized to locate more logic with
TimeAlarm. This will help it scale to more alarm types.

Merge pull request #2262 from jepler/cpb-speaker-disable
cpb: Disable the onboard speaker until request
2019-11-03 18:34:29 -05:00
jepler 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.

Closes: #2258
