Most of the AT91RM9200 user peripherals are also integrated into the
Atmel SAM9 range of processors.  This patch renames the headers from
at91rm9200_xx.h to at91_xx.h to indicate they're not
at91rm9200-specific.

The new SAM9-specific registers and register bits have also been
defined.

It also defines the AIC Fast-Forcing registers added to the AT91SAM9's.
