msm: kgsl: update KGSL to match most recent version
Over time chery-picks for KGSL have been skipped or
have been resolved differently between branches. As
a result, this branch of KGSL has become increasingly
difficult to maintain due to merge conflicts. With a
few exceptions KGSL should match the msm-3.4 mainline
exactly. To rectify the situation, this change brings
KGSL up-to-date with the msm-3.4 mainline as a bulk
change because cherry-picks are not practical.
