dt-bindings: clock: Introduce QCOM Graphics clock bindings

Qualcomm Graphics Clock & Reset Controller Binding

--------------------------------------------------

Required properties :

- compatible : shall contain "qcom,sdm845-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

- clock-names : shall be "xo"

Example:

	gpucc: clock-controller@5090000 {

		compatible = "qcom,sdm845-gpucc";

		reg = <0x5090000 0x9000>;

		#clock-cells = <1>;

		#reset-cells = <1>;

		#power-domain-cells = <1>;

		clocks = <&xo_board>;

		clock-names = "xo";

	};
