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

[Paul Parsons]

linux-2.6.32 changed the values of PXA_GPIO_IRQ_BASE and PXA_GPIO_IRQ_NUM from
64/128 to 96/192. This has broken the hx4700 platform, for example its PCMCIA/CF
driver. The 9 EGPIO GPIOs have become numbered 256..264, and consequently fail
the gpio_is_valid() test in gpiolib.c (which limits GPIOs to the range 0..255).
This patch reverts the values of PXA_GPIO_IRQ_BASE and PXA_GPIO_IRQ_NUM to their
previous linux-2.6.31 values for the hx4700 platform only.
