Subject: [PATCH] dt-bindings: clock: qcom,gcc-msm8953: split to separate schema

The Qualcomm MSM8953 GCC clock controller has clock inputs, thus
existing gcc-other.yaml was not describing it fully.  Move the binding
to its own schema file and document the clocks based on DTS.  Add driver
contributors as its maintainers.
