This function was in use to check if PSR feature got enabled. However on HSW and BDW we currently force psr exit by disabling EDP_PSR_ENABLE bit at EDP_PSR_CTL(dev). So this function was actually returning the active/inactive state that is different from the enable/disable meaning and had the risk of false negative. But anyway this check with DRRS was dangerous, since DRRS could try to get enabled before PSR gets there. So let's just remove it for now. A proper synchronization mechanism must be implemented later probably using pipe config.
