MLK-13723 imx7d: restore epdc QoS setting after exit the lpsr mode
without this patch, the QoS setting will be lost after exit LPSR mode. The patch moves the QoS setting into DDR setting group (in plugin mode), thus when exit LPSR mode, QoS setting will be restored as well as DDR setting. Signed-off-by: Robby Cai <robby.cai@nxp.com> (cherry picked from commit 0b217456375bace3fbe9a72c7e92a46dc1907277) (cherry picked from commit 75790929c674eea2f867b86a7734127d4cd45dfc)
