ARM: mxc: use ARCH_NR_GPIOS to define gpio number
The patch removes MXC_GPIO_IRQS and instead uses ARCH_NR_GPIOS to
define gpio number. This change is need when we change mxc gpio
driver to be device tree aware. When migrating the driver to device
tree, pdev->id becomes unusable. It requires driver get gpio range
from gpio core, which will dynamically allocates number from
ARCH_NR_GPIOS to 0.
As a bonus point, it removes lines of '#if' and make the code a
little bit cleaner. The side effect is the waste of number. But
this is not a point when we go single image.
