* RNG (Random Number Generator)

Required properties:
- compatible : Should be "qcom,msm-rng"
- reg        : Offset and length of the register set for the device
- qcom, msm_bus,name: Should be "msm-rng-noc"
- qcom, msm_bus,num_cases: Depends on the use cases for bus scaling
- qcom, msm_bus,num_paths: The paths for source and destination ports
- qcom, msm_bus,vectors: Vectors for bus topology.


Optional property:
- qcom,msm-rng-iface-clk : If the device uses iface-clk.

Example:

	qcom,msm-rng@f9bff000 {
		compatible = "qcom,msm-rng";
		reg = <0xf9bff000 0x200>;
		qcom,msm-rng-iface-clk;
		qcom,msm-bus,name = "msm-rng-noc";
		qcom,msm-bus,num-cases = <2>;
		qcom,msm-bus,num-paths = <1>;
		qcom,msm-bus,vectors-KBps =
				<1 618 0 0>,
				<1 618 0 800>;
	};
