Neil Armstrong cc2ccd19d9 drm/msm/adreno: fix a743 and a740 cx mem init
Disable the call to qcom_scm_gpu_init_regs() for a730 and a740
after init failures on the HDK8550 and HDK8450 platforms:
msm_dpu ae01000.display-controller: failed to load adreno gpu
msm_dpu ae01000.display-controller: failed to bind 3d00000.gpu (ops a3xx_ops [msm]): -5
msm_dpu ae01000.display-controller: adev bind failed: -5

While debugging, it happens the call to:
qcom_scm_gpu_init_regs(QCOM_SCM_GPU_ALWAYS_EN_REQ)
returns -5 and makes the gpu fail to initialize.

Remove the scm call since it's not done downstream either and
works fine without.

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.
