Zhan Liu 2d5ef0b42c drm/amd/display: Don't disable DP PHY when link loss happens
[Why]
There is a use case that link loss happens accidentally,
and we need to recover that link loss as soon as possible.
Under this circumstance, we will perform link training,
and try to recover the link that's just lost.

However, if link PHY is disabled before link training
happens, then DP display will never come back again.

Also, please note that dropping this disable_phy function
call won't break USB-C hotplug functionality.
(This line of code was firstly introduced associated with
a patch to fix USB-C hotplug issue)

[How]
Don't disable DP transmitter and its encoder before link
training happens, even if link loss is detected.

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.
