Dnyaneshwar Bhadane 43dea469e9 drm/i915/mtl: Add Wa_14019821291
This workaround is primarily implemented by the BIOS.  However if the
BIOS applies the workaround it will reserve a small piece of our DSM
(which should be at the top, right below the WOPCM); we just need to
keep that region reserved so that nothing else attempts to re-use it.

v2: Declare regs in intel_gt_regs.h (Matt Roper)

v3: Shift WA implementation before calculation of *base (Matt Roper)

v4:
-  Change condition gscpmi base to be fall in DSM range.(Matt Roper)

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.
