dt-bindings: clock: Merge qcom,gpucc-sm8350 into qcom,gpucc.yaml

The GPU clock controller bindings for the Qualcomm sm8350 platform are
not correct. The driver uses .fw_name instead of using indices to bind
parent clocks, thus demanding the clock-names usage. With the proper
clock-names in place, the bindings becomes equal to the bindings defined
by qcom,gpucc.yaml, so it is impractical to keep them in a separate
file.
