Anthony Koo 15ae3b28f8 drm/amd/display: disable link before changing link settings
[Why]
If link is already enabled at a different rate (for example 5.4 Gbps)
then calling VBIOS command table to switch to a new rate
(for example 2.7 Gbps) will not take effect.
This can lead to link training failure to occur.

[How]
If the requested link rate is different than the current link rate,
the link must be disabled in order to re-enable at the new
link rate.

In today's logic it is currently only impacting eDP since DP
connection types will always disable the link during display
detection, when initial link verification occurs.

README

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.
