[ Upstream commit f7b52890daba570bc8162d43c96b5583bbdd4edd ]
CG/PG ungate is already performed in ip_suspend_phase1. Otherwise,
the CG/PG ungate will be performed twice. That will cause gfxoff
disablement is performed twice also on runpm enter while gfxoff
enablemnt once on rump exit. That will put gfxoff into disabled
state.
