Subject: [PATCH 2/2] ACPI: x86: s2idle: Add another ID to s2idle_dmi_table

It's reported that "ASUSTeK COMPUTER INC. ROG Flow X16 GV601RW" has
non-functional fans after resume when using the AMD codepath.  This
issue is fixed using the Microsoft codepath.

Add the 3 variants of this system to the Microsoft codepath DMI table.
* GV601RW
* GV601RM
* GV601RE
