Device will be sent to sleep state during mmc runtime/system suspend and will be woken up during mmc runtime/system resume. By using this sequence the device doesn't need full initialization which gives 25% time reduction in system/runtime resume path. Also enable this feature along with mmc runtime PM for qualcomm controllers.
