Subject: [PATCH v4 7/7] acpi/x86: s2idle: Add a quirk for ASUSTeK COMPUTER INC. ROG Flow X13

ASUSTeK COMPUTER INC. ROG Flow X13 has a problem with fans upon wakeup from
s2idle. In examining the ASL, functions 3 and 4 are not called in the AMD
codepath but only in the Microsoft codepath.

Add the system to the quirk list to force Microsoft codepath.
