Subject: [PATCH] dt-bindings: clock: qcom,gcc-ipq6018: split to separate schema

The Qualcomm IPQ6018 GCC clock controller has clock inputs, thus existing
gcc-other.yaml was not describing it fully so move it to a separate schema.

Fully document the allowed and required XO and sleep clock inputs, as well
as update the provided example.
