[PATCH v1 03/10] drm/msm/a6xx: Avoid gmu lock in pm ops

[Akhil P Oommen]

We don't really need gmu lock in runtime pm ops because these operations
are serialized anyway and also with other paths where we take this lock.
This patch will help to simplify the locking order when we introduce
crashstate_lock in the upcoming patch.
