Damien George c9260dda23 rp2: Use local tinyusb instead of the one in pico-sdk. 
So that all MicroPython ports that use tinyusb use the same version.  Also
requires fewer submodule checkouts when building rp2 along with other ports
that use tinyusb.

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.
