Input: gpio-keys - add support for wakeup event action
Add support for specifying event actions to trigger wakeup when using the gpio-keys input device as a wakeup source. This would allow the device to configure when to wakeup the system. For example a gpio-keys input device for pen insert, may only want to wakeup the system when ejecting the pen.
