Add a required reset to the SDM845 UFS phy to express the PHY reset bit inside the UFS controller register space. Before this change, this reset was not expressed in the DT, and the driver utilized two different callbacks (phy_init and phy_poweron) to implement a two-phase initialization procedure that involved deasserting this reset between init and poweron. This abused the two callbacks and diluted their purpose. That scheme does not work as regulators cannot be turned off in phy_poweroff because they were turned on in init, rather than poweron. The net result is that regulators are left on in suspend that shouldn't be. This new scheme gives the UFS reset to the PHY, so that it can fully initialize itself in a single callback. We can then turn regulators on during poweron and off during poweroff.

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.
