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.

Commit f6ebff4fe810 ("drm/msm/adreno: De-spaghettify the use of memory
barriers") made some fixups relating to write arrival, ensuring that
the GPU's memory interface has *really really really* been told to come
out of reset. That in turn rendered the hacky commit being reverted no
longer necessary.

Get rid of it.

43ec1a202c drm/msm/adreno: De-spaghettify the use of memory barriers 
Memory barriers help ensure instruction ordering, NOT time and order
of actual write arrival at other observers (e.g. memory-mapped IP).
On architectures employing weak memory ordering, the latter can be a
giant pain point, and it has been as part of this driver.

Moreover, the gpu_/gmu_ accessors already use non-relaxed versions of
readl/writel, which include r/w (respectively) barriers.

Replace the barriers with a readback (or drop altogether where possible)
that ensures the previous writes have exited the write buffer (as the CPU
must flush the write to the register it's trying to read back).

14b27d5df3 drm/msm/a7xx: Initialize a750 "software fuse" 
On all Qualcomm platforms with a7xx GPUs, qcom_scm provides a method to
initialize cx_mem. Copy this from downstream (minus BCL which we
currently don't support). On a750, this includes a new "fuse" register
which can be used by qcom_scm to fuse off certain features like
raytracing in software. The fuse is default off, and is initialized by
calling the method. Afterwards we have to read it to find out which
features were enabled.

unclocked access if for some reason resuming of the DP controller fails.

Change the function to use pm_runtime_resume_and_get() and return an
error if resume fails.
