media: rc: gpio-ir-recv: Fix support for wake-up
[ 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.
