Subject: pc: Move s3/s4 suspend disabling to compat

RH-Author: Dr. David Alan Gilbert <dgilbert@redhat.com>
RH-MergeRequest: 155: 7.0 machine type fixes (x86)
RH-Commit: [26/26] 7d666032d5f5dab1444ebba085f92f2de4e86699
RH-Bugzilla: 2064771

Our downstream patches currently have tweaks in the C code to disable
s3/s4; Thomas pointed out we can just set the property.
