Werner Sembach 84d95f77f4 drm/i915/display: Restructure output format computation for better expandability
Couples the decission between RGB and YCbCr420 mode and the check if the
port clock can archive the required frequency. Other checks and
configuration steps that where previously done in between can also be done
before or after.

This allows for are cleaner implementation of retrying different color
encodings.

A slight change in behaviour occurs with this patch: If YCbCr420 is not
allowed but display is YCbCr420 only it no longer fails, but just prints
an error and tries to fallback on RGB.

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.
