Dropping CLK_GPUAPB simplifies OPP handling and avoids unnecessary
complexity.

I don't think this is correct, SM can disable the GPUAPB clock from the SM monitor:
>$ clock.w gpuapb off
Linux has to make sure the GPUAPB clock are enabled to access the GPU register, hence the clock have to be described in DT.
