FiiO M3K/X1000: add USB support

This only required a minor patch to the usb-designware driver due
to DMA requiring physical addresses -- on the X1000, these differ
from virtual addresses so we have to do the usual conversion.

Both the mass storage and HID drivers work, but there are a few
issues so this can't be considered 100% stable yet.

- Mass storage might not be detected properly on insertion,
  and USB has to be replugged before it shows up
- HID driver may occasionally panic or hang the machine
