dt-bindings: clock: qcom,sm6125-dispcc: reference qcom,gcc.yaml

Just like most of Qualcomm clock controllers, we can reference common
qcom,gcc.yaml schema to unify the common parts of the binding. This
also adds the '#reset-cells' property which is permitted for the
SM6125 SoC clock controllers, but not listed as a valid property.

Fixes: bb4d28e377 ("arm64: dts: qcom: sm6125: Add missing MDSS core reset")
