Martin Tsai bfeefe6ea5 drm/amd/display: should support dmub hw lock on Replay
[Why]
Without acquiring DMCUB hw lock, a race condition is caused with
Panel Replay feature, which will trigger a hang. Indicate that a
lock is necessary to prevent this when replay feature is enabled.

[How]
To allow dmub hw lock on Replay.

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.
