José Roberto de Souza c4298d1577 drm/i915/display/mtl: Program latch to phy reset
Latch reset of phys during DC9 and when driver is unloaded to avoid
phy reset.

Specification ask us to program it closer to the step that enables
DC9 in DC_STATE_EN but doing this way allow us to sanitize the phy
latch during driver load.

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.
