(Probably going to want a "convert to PR2040" option sometime after this)

For the SparkFun RP2040 ProMicro board? Yeah. On my radar. Got 4 of them handy already.
We'll need a ChibiOS upgrade first, anyway. Unsure we want the 21.6.x ChibiOS with the 20.3.x ChibiOS-Contrib, though.

This also unblocks #14420, but I guess that's not as fun as the 2040 :P

Current chibios @ 413e39c does not contain any RP2040 related changes yet.
So we have to update ChibiOS at the same time with the contrib.

I noticed recent ChibiOS migrated ChibiOS/os/common/ports/ARMCMx/* files into own directories.
The PORT_V in chibios.mk have to be updated to match to new directories.

I found a bug in the usb driver for RP2040 in the contrib and made PR.

Updated my RISC-V port for 21.6 as well in ChibiOS/ChibiOS-Contrib#302

[tzarc]

Cancelling this for now. Will sort out the upgrade to 21.6.x with the existing in-flight PR for that upgrade.
