Stanley Chu 561e3a8726 scsi: ufs-mediatek: Fix unbalanced clock on/off
MediaTek UFS clocks are separated to two parts and controlled by different
modules: ufs-mediatek and phy-ufs-mediatek.

If both Auto-Hibern8 and clk-gating feature are enabled, mphy power control
is not balanced thus unbalanced control also happens to the clocks probed
by phy-ufs-mediatek module.

Fix this issue by:

 - Promise usage of phy_power_on/off balanced

 - Remove phy_power_on/off control in suspend/resume vops since both can be
   handled in setup_clock vops only

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
