gpiolib: acpi: Add a quirk for Asus UM325UAZ

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.
