Gregory Fong 3afa129a9d gpio: brcmstb: support wakeup from S5 cold boot 
For wake from S5, we need to:
- register a reboot handler
- set wakeup capability before requesting IRQ so wakeup count is
  incremented
- mask all GPIO IRQs and clear any pending interrupts during driver
  probe to since no driver will yet be registered to handle any IRQs
  carried over from boot at that time, and it's possible that the
  booted kernel does not request the same IRQ anyway.

This means that /sys/.../power/wakeup_count is valid at boot time, and
we can properly account for S5 wakeup stats. e.g.:

  ### After waking from S5 from a GPIO key
  # cat /sys/bus/platform/drivers/brcmstb-gpio/f04172c0.gpio/power/wakeup
  enabled
  # cat /sys/bus/platform/drivers/brcmstb-gpio/f04172c0.gpio/power/wakeup_count
