[PATCH v2] pxa/hx4700: Fix PXA_GPIO_IRQ_BASE/IRQ_NUM values

[Paul Parsons]

The hx4700 platform has 70 board gpios: 64 ASIC3 gpios numbered 192..255, and
8 EGPIO gpios numbered 256..263 (plus a 9th which is not used).
Thus the new CONFIG_ARCH_NR_GPIO config option must be set to 264.

V2:
Use new CONFIG_ARCH_NR_GPIO config option instead of modifying PXA_GPIO_IRQ_BASE
and PXA_GPIO_IRQ_NUM #defines.
Rebased to linux-3.3-rc1.
