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.
