Due to the sync_state is enabled by default in pmdomain & CCF since v6.17,

gpucc-x1e80100 3d90000.clock-controller: sync_state() pending due to 3d6a000.gmu
In order to fix this state and allow the GMU to be properly
probed, let's add a proper driver for the GMU and add it to
the MSM driver components.
Only the proper GMU has been tested since I don't have
access to hardware with a GMU wrapper.

Niel,
Could you please send the follow up revision of this patch? Lets get
this fix merged.
I'm really struggling on the separate_gpu_kms part, it's not trivial at all.
I'll try again and report my current status.
