On chromebook kevin, we are using gpio-keys for pen insert event. But
we only want it to wakeup the system when ejecting the pen.

So we may need to change the interrupt trigger type during suspending.

Changes in v4:
Add dt-binding gpio-keys.h, stop saving irq trigger type, add enable/disable wakeup helpers as Dmitry suggested.
Include dt-binding gpio-keys.h

Changes in v3:
Adding more comments as Brian suggested.

Changes in v2:
Specify wakeup event action instead of irq trigger type as Brian
suggested.
Specify wakeup event action instead of irq trigger type as Brian
suggested.
Specify wakeup event action instead of irq trigger type as Brian
suggested.
