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.

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

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.
