MIPS: PowerTV: Separate PowerTV USB support from non-USB code

Browse source 
Separate USB code into a file separate from asic/asic_devices.

Separating the USB code from everything else in asic/asic_devices.c goes
a long way toward reducing the use of that file as a dumping ground for
everything that didn't seem to fit anywhere else.
