[ Upstream commit a07f8b9983543d465b50870ab4f845d4d710ed3f ]
[Why]
Otherwise SMU won't mark Display as idle when trying to perform s2idle.
[How]
Mark the bit in the dcn31 codepath, doesn't apply to older ASIC.
It needed to be split from phy refclk off to prevent entering s2idle
when PSR was engaged but driver was not ready.

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.
