We have a chance to fix this to Rob's liking, so please make this
"qcom,sdm845-rpmh-clock" (or maybe "qcom,sdm845-rpmhcc"?)

I believe the clock-controller, the power-domain and the bus-scaler are
equal contenders of the label "rpmh", so please make it more specific.
How about "rpmhcc" to mimic previous platforms?
