This just adds recognition for the Atmel AT91 USB peripheral controller.
(And a missing check for the Samsung S3C2410.) This PIO-only hardware
is used in a variety of chips, including the at91rm9200. (That one has
an MMU and runs "regular Linux".)
Please merge; the patch is against your current BK.

p.s. In case anyone's curious: this is at least the sixth different ARM
based System-On-Chip processor that works in this API framework. If
many folk were working with the SA-1100 any more, there'd be seven ... ;)
Add declarations to recognize the AT91 USB peripheral controller,
as used in various ARMv4T chips including the mmu-ful at91rm9200.
