[ARM] 3711/1: AT91 timer update

Patch from Andrew Victor

The AIC interrupt controller is the same on the Atmel AT91RM9200,
AT91SAM9261 and AT91SAM9260 processors.

This patch removes any RM9200-specific naming from the IRQ driver, and
moves the AT91RM9200's default IRQ priority table into at91rm9200.c.
