[ Upstream commit 9c592f8ab114875fdb3b2040f01818e53de44991 ]
The driver was intended from the start to be a wake-up source for the system, however due to the absence of a suitable call to device_set_wakeup_capable(), the device_may_wakeup() call used to decide whether to enable the GPIO interrupt as a wake-up source would never happen. Lookup the DT standard "wakeup-source" property and call device_init_wakeup() to ensure the device is flagged as being wakeup capable.
