Revert "drm/msm/a6xx: Poll for GBIF unhalt status in hw_init"

Browse Source 
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.
