pcmcia: CompactFlash driver for PA Semi Electra boards

Driver for the CompactFlash slot on the PA Semi Electra eval board. It's
a simple device sitting on localbus, with interrupts and detect/voltage
control over GPIO.

The driver is implemented as an of_platform driver, and adds localbus
as a bus being probed by the of_platform framework.
