Asus UM325UAZ has GPIO 18 programmed as both an interrupt and a wake source, but confirmed with internal team on this design this pin is floating and shouldn't have been programmed. This causes lots of spurious IRQs on the system and horrendous battery life. Add a quirk to ignore attempts to program this pin on this system.
