de43b500bd py/runtime: Allow initialising sys.path/argv with defaults.
If MICROPY_PY_SYS_PATH_ARGV_DEFAULTS is enabled (which it is by default)
then sys.path and sys.argv will be initialised and populated with default
values.  This keeps all bare-metal ports aligned.

86ce442607 ports: Add '.frozen' as the first entry in sys.path.
Frozen modules will be searched preferentially, but gives the user the
ability to override this behavior.

This matches the previous behavior where "" was implicitly the frozen
search path, but the frozen list was checked before the filesystem.

f21c565583 rp2/machine_uart: Handle and clear UART RX timeout IRQ.
The pico-sdk 1.3.0 update in 97a7cc243b
introduced a change that broke RP2 Bluetooth UART, and possibly UART in
general, which stops working right after UART is initialized.  The commit
raspberrypi/pico-sdk@2622e9b enables the UART receive timeout (RTIM) IRQ,
which is asserted when the receive FIFO is not empty, and no more
characters are received for a period of time.

This commit makes sure the RTIM IRQ is handled and cleared in
uart_service_interrupt.

172a031dff rp2/boards/PIMORONI_PICOLIPO_16MB: Fix 16MB flash size.
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.

0a9335ecaa rp2/rp2_pio: Support exec with sideset.
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.

b6dbbbe82f rp2/machine_i2s: Add I2S protocol support.
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)

af64c2ddbd extmod/machine_pwm: Factor out machine.PWM bindings to common code.
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.

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).

feb7e2e864 rp2/machine_rtc: In RTC.datetime, compute weekday automatically.
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.
