+- fsl,pmic-stby-poweroff: Configure CCM to assert PMIC_STBY_REQ signal

+ Use this property if the SoC should be powered off by external power

The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx6qdl-clock.h
for the full list of i.MX6 Quad and DualLite clock IDs.
