Robin Chen c84ff24a77 drm/amd/display: Pass DSC slice height to PSR FW
[Why]
When DSC is enabled, the PSRSU seletive update region
must be multiple number of DSC slice height number.
The original solution is to overwrite the SU Y granularity
by DSC slice height in DAL driver. However, the size
of the SU Y granularity variable only has 8 bytes
and the DSC slice height may over the 8 bytes size.

[How]
Instead of overwriting the SU Y granularity value,
add a new DSC slice height pararmeter and pass it
to DMUB PSRSU FW. The PSRSU FW will refer to the
DSC slice height value and extend the SU region.

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.
