drm/msm/a6xx: Remove both GBIF and RBBM GBIF halt on hw init
Currently we're only deasserting REG_A6XX_RBBM_GBIF_HALT, but we also
need REG_A6XX_GBIF_HALT to be set to 0.
This is typically done automatically on successful GX collapse, but in
case that fails, we should take care of it.
Also, add a memory barrier to ensure it's gone through before jumping
to further initialization.
