  Linux should apparently not be concerned with gcc_gpu_bimc_gfx_src_clk and
gcc_gpu_bimc_gfx_src_clk on MSM8998, as they're preconfigured for us.
Unregister them to prevent issues.

You mention the bimc_gfx clock twice here.  One of them has to be a typo.

Also, can you clarify the reasoning?  The RCG is controlled by the RPM, 
but the branch clock is under the control of Linux.
