PCMCIA: pxa: convert PXA socket drivers to use new irq/gpio management

Browse Source 
Convert all the PXA platform socket drivers to use the new irq/gpio
management provided by soc_common.  This relieves these drivers from
having to do anything with these GPIOs other than provide the numbers
to soc_common.
