Input: xpad - restore LED state after device resume
[ Upstream commit a1fbf5bbef025b4844162b3b8868888003a7ee9c ] Set the LED_CORE_SUSPENDRESUME flag on our LED device so the LED state will be automatically restored by LED core on resume. Since Xbox One pads stop flashing only when reinitialized, we'll send them the initialization packet so they calm down too.
