Tim Radvan	f842a40df4	rp2/rp2_pio: Add fifo_join support for PIO. The PIO state machines on the RP2040 have 4 word deep TX and RX FIFOs. If you only need one direction, you can "merge" them into either a single 8 word deep TX or RX FIFO. We simply add constants to the PIO object, and set the appropriate bits in `shiftctrl`.

rp2/rp2_pio: Add fifo_join support for PIO.

The PIO state machines on the RP2040 have 4 word deep TX and RX FIFOs.  If
you only need one direction, you can "merge" them into either a single 8
word deep TX or RX FIFO.

We simply add constants to the PIO object, and set the appropriate bits in
`shiftctrl`.

Resolves #6854.

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.
