Bug Description
[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.
