mb/google/volteer: Add gpio-keys ACPI node for PENH
Use gpio_keys driver to add ACPI node for pen eject event. Also
setting gpio wake pin for wake events.
Removal and insertion (both edges) triggers IRQ and only removal is a
wake event (rising edge).
Adding for both Volteer and Volteer2 variants.
BUG=b:146083964
BRANCH=None
TEST=tested on a Volteer
