If the power-button is pressed to wakeup the laptop/tablet from suspend and we report a KEY_POWER event to userspace when woken up this will cause userspace to immediately suspend the system again which is undesirable. This commit sets the new no_wakeup_events flag in the gpio_keys_button struct for the power-button suppressing the undesirable KEY_POWER input events on wake-up.
