MLK-18161-12 imx8qm/imx8qxp - Power down devices enabled by uboot before launching the  kernel

Make sure that all devices that are powered up by uboot
are powered down before bringing up kernel.
Else the subsystem/device will never be powered down by SCFW even though
from the kernel's point of view it should be powered down.

Benefiting from power domain driver, We have implemented the function "power_off_pd_devices"
to power off all active devices. No need to explicitly power off them in board_quiesce_devices.
