Subject: [PATCH v2 4/6] acpi/x86: s2idle: Add a quirk for ASUS TUF Gaming A17 FA707RE

ASUS TUF Gaming A17 FA707RE has problems with ACPI events after
s2idle resume.  It's from a missing call to an ASL method in AMD
the s2idle calling path. Force the system to use the Microsoft
Modern Standby calling path instead.
