mainlining shenanigans

[Why] We currently don't do DC validation for medium or full updates where the plane state isn't created. There are some medium and full updates that can cause bandwidth or clock changes to occur resulting in underflow or corruption. We need to be able to fill surface and plane info updates during atomic commit for dm_determine_update_type for commit. Since we already do this during atomic commit tail it would be good if we had the same logic in both places for creating these structures. [How] Introduce fill_dc_scaling_info and fill_dc_plane_info_and_addr. These two functions cover the following three update structures: - struct dc_scaling_info - struct dc_plane_info - struct dc_plane_address Cleanup and adapter the existing fill_plane_* helpers to work with these functions. Update call sites that used most of these sub helpers directly to work with the new functions. The exception being prepare_fb - we just want the new buffer attributes specifically in the case where we're creating the plane. This is needed for dc_commit_state in the case where the FB hasn't been previously been used. This isn't quite a refactor, but functionally driver behavior should be mostly the smae as before. The one exception is that we now check the return code for fill_plane_buffer_attributes which means that commits will be rejected that try to enable DCC with erroneous parameters.

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.
