Introduce support for the SC7280 platform and specifically the RB3 Gen 2
development board.

The RB3 Gen 2 is the latest robotics board from Qualcomm, featuring a
QCM6490 SoC (the same SoC found in the Fairphone 5), 6GB of RAM, and
128GB of UFS storage, as well as a whole lot of I/O.

Most of the I/O is attached via a custom PCIe bridge chip, and as such
is not yet supported. However it is possible to boot from USB via the
Type-C port, which is hardcoded to host mode for this initial support.

USB support additionally requires this patch:
