Was incorrectly added as 7MB for an 8MB SPI flash, but this board has a
16MB chip, not 8MB, so it should be 15MB leaving 1MB for MicroPython.

The rp2.StateMachine.exec errors when supplying a sideset action. This
commit passes the sideset_opt from the StateMachine though to the parser.
It also adds some value validation to the sideset operator.
Additionally, the "word" method is added to the exec to allow any other
unsupported opcodes.
Fixes issue #7924.
This commit adds I2S protocol support for the rp2 port:
- I2S API is consistent with STM32 and ESP32 ports
- I2S configurations supported:
- master transmit and master receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequency
- 3 modes of operation:
- blocking
- non-blocking with callback
- uasyncio
- internal ring buffer size can be tuned
- DMA IRQs are managed on an I2S object basis, allowing other
RP2 entities to use DMA IRQs when I2S is not being used
- MicroPython documentation
- tested on Raspberry Pi Pico development board
- build metric changes for this commit: text(+4552), data(0), bss(+8)

This is an stm32-specific feature that's accessed via the pyb module, so
not something that will be widely enabled.

This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.
Optionally supports a board.md for additional customisation of the
download page, as well as deploy.md for flashing instructions.

This commit refactors machine.PWM and creates extmod/machine_pwm.c. The
esp8266, esp32 and rp2 ports all use this and provide implementations of
the required PWM functionality. This helps to reduce code duplication and
keep the same Python API across ports.
This commit does not make any functional changes.

The zephyr port doesn't support SoftI2C so it's not enabled, and the legacy
I2C constructor check can be removed.

To keep things neat and tidy, we ensure that each file has 1 and only 1
newline at the end of each file.

Flash erase/program functions disable the XIP bit. If any code runs from
flash at the same time (eg an IRQ or code it calls) it will fail and cause
a lockup.
Prior to this fix, if the UART hardware FIFO had a few chars but still
below the FIFO trigger threshold, and the ringbuf was empty, the read
function would timeout if timeout==0 (the default timeout).
This fix follows the suggestion of @iabdalkader.
The RX IRQ does not trigger if the FIFO is less than the trigger level, in
which case characters may be available in the FIFO, yet not in the ringbuf,
and the ioctl returns false.
These warnings appear with GCC 11. Keep them as warnings but not as
compiler errors so they can be dealt with properly in the future.

Calculating the weekday each time you want to set a date is error prone and
tiresome. MicroPython can do it on its own - hardware on some ports do not
support storing weekday in hardware and always computes it on the fly,
ignoring the value given to the constructor.
During discussion for #7432 the conclusion was that there seems to be no
obvious reason to let user set the weekday to an incorrect value so it
makes sense to just ignore the provided weekday value and always compute
the correct value. This patch introduces this change for the rp2 port.

The RTC in rp2 can store any, even wrong, number as a weekday in RTC. It
was, however, discussed in #7394 that we would like to unify all ports and
use 0 as Monday, not Sunday in the machine.RTC implementation.
This patch makes sure that the default date set in RTC is adheres to this
convention. It also fixes the example in quickref to use proper weekday to
avoid confusion.

The rtc_set_datetime() from pico-sdk will validate the values in the
datetime_t structure and refuse to set the time if they aren't valid. It
makes sense to raise an exception if this happens instead of failing
silently which might be confusing (as an example, see:
https://github.com/micropython/micropython/pull/6928#issuecomment-860166044
).
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.
The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15
roadmap on #6832.
