robert-hh 1be74b94b6 rp2/machine_uart: Add buffered transfer of data with rxbuf/txbuf kwargs.
Instantiation and init now support the rxbuf and txbuf keywords for setting
the buffer size.  The default size is 256 bytes.  The minimum and maximum
sizes are 32 and 32766 respectively.

uart.write() still includes checks for timeout, even if it is very unlikely
to happen due to a) lack of flow control support and b) the minimal timeout
values being longer than the time it needs to send a byte.

This brings the port's configuration closer to the stm32 and esp32 ports.

Damien George 53f5bb05a9 rp2,stm32: Enable MICROPY_PY_UBINASCII_CRC32 to get ubinascii.crc32().
These ports already have uzlib enabled so this additional ubinascii.crc32
function only costs about 90 bytes of flash.

Damien George 195e7dfa06 rp2/modmachine: Implement additional functions incl unique_id and idle.
Added functions in the machine module are:
- unique_id (returns 8 bytes)
- soft_reset
- idle
- lightsleep, deepsleep (not power saving at the moment)
- disable_irq, enable_irq
- time_pulse_us

Damien George 469345e728 rp2: Add new port to Raspberry Pi RP2 microcontroller.
This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.

The build system uses pure cmake (with a small Makefile wrapper for
convenience).  The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented.  Some examples are provided
in the examples/rp2/ directory.

Work done in collaboration with Graham Sanderson.
