drm/msm/a6xx: Send ACD state to QMP at GMU resume

Browse source

The QMP mailbox expects to be notified of the ACD (Adaptive Clock
Distribution) state. Get a handle to the mailbox at probe time and
poke it at GMU resume.

Since we don't fully support ACD yet, hardcode the message to "val: 0"
(state = disabled).
