[ARM] 3675/2: Preparing for AT91SAM926 support

Patch from Andrew Victor This prepares the way for adding support for the new Atmel AT91SAM926x processors. Major changes: - Rename time.c to at91rm9200_time.c - Rename common.c to at91rm9200.c - Introduce ARCH_AT91, of which ARCH_AT91RM9200, ARCH_AT91SAM9260 and ARCH_AT91SAM9261 are dependent.
