[PATCH 6.0 12/17] gpiolib: acpi: Add a quirk for Asus UM325UAZ

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Mario Limonciello <mario.limonciello@amd.com>

commit 0ea76c401f9245ac209f1b1ce03a7e1fb9de36e5 upstream.

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.
