drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO functionality
This adds (well, re-adds actually) handling for events/IRQs through cs5535 GPIOs. In the wild and wooly world of CS5535, setup_event() is for assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the pair to trigger IRQs. These should really only be used in highly platform-specific drivers (such as OLPC's DCON driver). Sadly, because set_irq() uses MSRs, this causes the driver to become X86-specific.
