ACPI: x86: s2idle: Add module parameter to prefer Microsoft GUID

Browse source

OEMs have made some mistakes in the past for the AMD GUID support
and not populated the method properly.  To add an escape hatch for
this problem introduce a module parameter that can force using
the Microsoft GUID.

This is intentionally introduced to both Intel and AMD codepaths
to allow using the parameter as a debugging tactic on either.
