Public bug reported:

[Impact]
Several AMD based OEM designs have spurious wakeups occurring from EC events 
during s2idle.  This leads to non-functional wakeup sources or higher power 
consumption.

[Fix]
Prevent setting the GPE for the EC for wakeup source on AMD systems.

[Test]
Verify s2idle on OEM system.

[Where problems could occur]
Code is guarded to only run on AMD systems, which are just now getting s2idle 
support in oem kernel.
