Stanislav Lisovskiy 764b1c8df4 drm/i915: Implement UHBR bandwidth check
According to spec, we should check if output_bpp * pixel_rate is less
than DDI clock * 72, if UHBR is used.

v2: - s/pipe_config/crtc_state/ (Jani Nikula)
    - Merged previous patch into that one, to remove empty function(Jani Nikula)

v3: - Make that constraint check to be DSC-related only
    - Limit this to only DISPLAY_VER <= 13

v4: - Move constraint check to the top(Vinod Govindapillai)

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.
