PCMCIA: soc_common: add GPIO support for card status signals
Add GPIO support for reading the card status (card detect, ready, battery voltage detect) signals into soc_common code. As we want interrupts from these GPIOs, this takes over the old irq handling infrastructure for card status signals, which will now be managed entirely by the soc_common code.
