[PATCH 3/3] twl4030: enable wakeup on twl4030 IRQ.

[NeilBrown]

Most of the interrupts that come through this line should trigger
wakeups:
  power button
  RTC alarm
  power available
  usb plug/unplug

so mark the interrupt as a wakeup interrupt.
This is particularly important for when the interrupt arrives during
the late suspend phase.  Without this setting it will be ignored.
