Subject: [PATCH v6 03/15] dt-bindings: clock: document qcom,gcc-ipq8064 binding

Document qcom,gcc-ipq8064 binding needed to declare pxo and cxo source
clocks. The gcc node is also used by the tsens driver, already documented,
to get the calib nvmem cells and the base reg from gcc. Use
qcom,gcc.yaml as a template and remove the compatible from
generic qcom,gcc-other.yaml
