The GPUCC clock provider have a bunch of generic properties that
are needed in a device tree. Add a YAML schemas for those.

-Qualcomm Graphics Clock & Reset Controller Binding
---------------------------------------------------
-
-Required properties :
-- compatible : shall contain "qcom,sdm845-gpucc" or "qcom,msm8998-gpucc"
-- reg : shall contain base register location and length
-- #clock-cells : from common clock binding, shall contain 1
-- #reset-cells : from common reset binding, shall contain 1
-- #power-domain-cells : from generic power domain binding, shall contain 1
-- clocks : shall contain the XO clock
- shall contain the gpll0 out main clock (msm8998)
-- clock-names : shall be "xo"
- shall be "gpll0" (msm8998)
-
-Example:
- gpucc: clock-controller@5090000 {
- compatible = "qcom,sdm845-gpucc";
- reg = <0x5090000 0x9000>;
- #clock-cells = <1>;
- #reset-cells = <1>;
- #power-domain-cells = <1>;
- clocks = <&rpmhcc RPMH_CXO_CLK>;
- clock-names = "xo";
- };
