sdm: Set connector mode on power off

CRTC ROI is set to full screen during power off. if SetActiveConfig()
called before SetPowerMode off, CRTC ROI is set to full screen based
on old resolution mode which results in failure. Hence set the new
connector mode as a part of SetPowerMode to avoid this.
