[ARM] Fix suspend oops caused by PXA2xx PCMCIA driver
The PXA2xx PCMCIA driver was registering a device_driver with the platform_bus_type. Unfortunately, this causes data outside the device_driver structure to be dereferenced as if it were a platform_driver structure, causing an oops. Convert the PXA2xx core driver to use the proper platform_driver structure. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
