Skyrim: Keep retimer enabled in suspend
The A1 retimer needs to remain enabled in suspend in order to prevent
issues with USB detection on resume. Enable and disable on the
transition into/out of S5 instead.
BUG=b:273849234,b:280957965
TEST=on frostflow, ensure USB file transfer is able to resume after
suspend
