Hi,
This series allow vendors to keep the regulator always-on, and provide an implementation on MediaTek UFS platforms.

Introduce a flag "always_on" in struct ufs_vreg to allow vendors
to keep the regulator always-on.

For some devices which needs extra delay after VCC power down,
VCC shall be kept always-on in some MediaTek UFS platforms to
ensure the stability of such devices because the extra delay may
not be enough in those platforms.
