[ARM] 3587/1: AT91RM9200 hardware headers

Patch from Andrew Victor

These headers define the registers and bits for the SPI (Serial
Peripheral Interface), SSC (Synchronous Serial), TC (Timer/Counter) and
UDP (USB Device) peripherals integrated in the AT91RM9200 processor.

(They will probably also be usable for the AT91SAM9 series of SoC
processors)
