This patch makes the AT91 gpio.c support processor-generic (AT91RM9200
and AT91SAM9xxx).  The GPIO controllers supported by a particular AT91
processor are defined in the processor-specific file and are registered
with gpio.c at startup.

This is more preparation for adding support for the new Atmel AT91SAM9
processors.

Changes include:
- Replace AT91_BASE_* with AT91RM9200_BASE_*
- Replace AT91_ID_* with AT91RM9200_ID_*
- ROM, SRAM and UHP address definitions moved to at91rm9200.h.
- The raw AT91_P[ABCD]_* definitions are now depreciated in favour of
the GPIO API.

The ARM Versatile board PCI config space read routines are broken for byte

The ARM XIP_KERNEL map created in devicemaps_init() is wrong.
The map.pfn is rounded down to an even 1MiB section boundary
which results in va/pa translations errors when XIP_PHYS_ADDR
starts on an odd 1MiB boundary and this causes the kernel to
hang.  This patch fixes ARM XIP_KERNEL translation errors for
the odd 1MiB XIP_PHYS_ADDR boundary case.

In OMAP2420, an incoming GPIO interrupt always sets both GPIO_IRQSTATUS1
and GPIO_IRQSTATUS2, even if the relevant bit is disabled in
GPIO_IRQENABLE1/2 and DSP doesn't use GPIO at all. GPIO_IRQSTATUS1
is for MPU and GPIO_IRQSTATUS2 is for DSP. If IRQSTATUS is set, this
will prevent the system from going to idle state. This patch also clears
IRQSTATUS2 to avoid the above situation.
