Commit c9707bcbd0f3 ("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.
This reverts commit b77532803d11f2b03efab2ebfd8c0061cd7f8b30.
