[PATCH 06/19] PCMCIA: sa11x0: cerf: convert to use new irq/gpio management

[Russell King - ARM Linux]

Convert Cerf socket driver to use the new irq/gpio management.
This is slightly more involved because we have to touch the private
platform header file to modify the GPIO bitmasks to be GPIO numbers.
