Akhil P Oommen f691636311 drm/msm/a6xx: Fix out of bound IO access in a6xx_get_gmu_registers
commit 779b68a5bf2764c8ed3aa800e41ba0d5d007e1e7 upstream.

REG_A6XX_GMU_AO_AHB_FENCE_CTRL register falls under GMU's register
range. So, use gmu_write() routines to write to this register.

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.
