Recently I contributed the switch to OPP API for all Adreno generations.
I did however also skip over the fact that GPUs with a GMU don't specify
a core clock of any kind in the GPU node. While that didn't break
anything, it did introduce unwanted spam in the dmesg:

adreno 5000000.gpu: error -ENOENT: _opp_set_clknames: Couldn't find clock with name: core_clk

Guard the entire logic so that it's not used with GMU-equipped GPUs.
