4.7-stable review patch. If anyone has any objections, please let me know.

------------------

From: Peter Chen <peter.chen@xxxxxxx>

commit f5a49057c71433e35a4712ab8d8f00641b3e1ec0 upstream.

There is a missing BM_CLPCR_BYP_MMDC_CH0_LPM_HS setting for imx6ul,
without it, the "standby" mode can't work well, the system can't be
resumed.

With this commit, the "standby" mode works well.
