Ville Syrjälä d7cc4b6bc9 drm/i915/dsc: Add prefill helper for DSC
Add intel_vdsc_prefill_lines() which tells us how many extra lines
of latency the DSC adds to the pipe prefill.

We shouldn't need a "worst case" vs, "current case" split here
as the DSC state should only change during full modesets.

The returned numbers are in .16 binary fixed point.

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 reStructuredText 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.
