scsi: ufs: ufs-mediatek: Disable unused VCCQx power rails

Browse source

Some MediaTek UFS platforms support different VCCQx power rails, for
example, both 1.2v and 1.8v VCCQx, in a single kernel image.

To optimize the system power consumption, provide a way to disable and
release the unused power rail during the device probing.
