Johan Hovold 31203f5680 drm/msm/a6xx: fix bogus hwcg register updates 
commit dedb897f11 upstream.

The hw clock gating register sequence consists of register value pairs
that are written to the GPU during initialisation.

The a690 hwcg sequence has two GMU registers in it that used to amount
to random writes in the GPU mapping, but since commit 188db3d7fe
("drm/msm/a6xx: Rebase GMU register offsets") they trigger a fault as
the updated offsets now lie outside the mapping. This in turn breaks
boot of machines like the Lenovo ThinkPad X13s.

Note that the updates of these GMU registers is already taken care of
properly since commit 40c297eb24 ("drm/msm/a6xx: Set GMU CGC
properties on a6xx too"), but for some reason these two entries were
left in the table.

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.
