PCMCIA: pxa: convert PXA socket drivers to use new irq/gpio management
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. Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
