Qualcomm MSM Clock controller

Qualcomm MSM Clock controller devices contain PLLs, root clock generators
and other clocking hardware blocks that provide stable, low power clocking to
hardware blocks on Qualcomm SOCs. The clock controller device node lists the
power supplies needed to be scaled using the vdd_*-supply property.

Minor differences between hardware revisions are handled in code by re-using
the compatible string to indicate the revision.

Required properties:
- compatible:		Must be one of "qcom,gcc-<target>",
			"qcom,mmsscc-<target>", "qcom,debugcc-<target>" or
			"qcom,lpasscc-<target>". <target> is the name of the
			Qualcomm SoC.
- reg:			Pairs of physical base addresses and region sizes of
			memory mapped registers.
- reg-names:		Names of the bases for the above registers. Currently,
			there is one expected base: "cc_base"

Optional properties:
- vdd_dig-supply:	The digital logic rail supply.
- #clock_cells:		If this device will also be providing controllable
			clocks, the clock_cells property needs to be specified.
			This will allow the common clock device tree framework
			to recognize _this_ device node as a clock provider.

Example:
	clock_rpm: qcom,rpmcc@fc4000000 {
		compatible = "qcom,rpmcc-8974";
		reg = <0xfc400000 0x4000>;
		reg-names = "cc_base";
		#clock-cells = <1>;
	};

	clock_gcc: qcom,gcc@fc400000 {
		compatible = "qcom,gcc-8974";
		reg = <0xfc400000 0x4000>;
		reg-names = "cc_base";
		vdd_dig-supply = <&pm8841_s2_corner>;
		#clock-cells = <1>;
	};
