This adds USB console support for the Purism L5. Other kernels that have gadget_f_acm support should also work.

I've applied it on top of

#53

The old kernel has an issue with MMC failing to come up sometimes, it's
resolved in later kernels. 5.12.2pureos3 is the latest kernel release
from Purism.
Initialize the USB gadget first then initialize the serial console.
Point the setup functions to the correct serial port.
