PCMCIA: sa11x0: h3600: convert to use new irq/gpio management
Convert iPAQ socket driver to use the new irq/gpio management. As this already uses the GPIO subsystem, these changes are localized to just the PCMCIA directory. Acked-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
