1f800cac3c rp2/micropy_rules.cmake: Fix makemoduledefs vpath to work with abs path.
In particular the firmware can now be built in a build directory that lives
outside the source tree, and the py/modarray.c file will still be found.

See issue #6837.

7f7b4f2bc6 rp2/machine_adc: Only initialise the ADC periph if not already enabled.
Otherwise it resets the ADC peripheral each time a new ADC object is
constructed, which can reset other state that has already been set up.

See issue #6833.

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

7a9027fd5d rp2/rp2_pio: Add JMP PIN support for PIO.
PIO state machines can make a conditional jump on the state of a pin: the
`JMP PIN` command.  This requires the pin to be configured with
`sm_config_set_jmp_pin`, but until now we didn't have a way of doing that
in MicroPython.

This commit adds a new `jmp_pin=None` argument to `StateMachine`.  If it is
not `None` then we try to interpret it as a Pin, and pass its value to
`sm_config_set_jmp_pin`.

c9210a65df rp2/machine_pin: Change N_GPIOS to NUM_BANK0_GPIOS for pico-sdk compat.
This fixes machine_pin.c to build against the new pico-sdk coming down the
pipeline, whilst still working with the existing version.

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.
