mainboard/google/parrot: fix ACPI interrupt storm on lid switch change
This fixes the ACPI interrupt storm on Parrot that happens when
closing the lid or entering suspend by lid close (seen in
/sys/firmware/acpi/interrupts/gpe1F). This patch inverts the interrupt
trigger level every time the interrupt is received so that it doesn't fire
until the next state change. http://askubuntu.com/questions/310196
is a good example of what this is trying to solve.
