dt-bindings: rng: ti,omap-rom-rng: convert OMAP ROM RNG to dtschema

OMAP ROM RNG driver binding

Secure SoCs may provide RNG via secure ROM calls like Nokia N900 does. The

implementation can depend on the SoC secure ROM used.

- compatible:

	Usage: required

	Value type: <string>

	Definition: must be "nokia,n900-rom-rng"

- clocks:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: reference to the the RNG interface clock

- clock-names:

	Usage: required

	Value type: <stringlist>

	Definition: must be "ick"

Example:

	rom_rng: rng {

		compatible = "nokia,n900-rom-rng";

		clocks = <&rng_ick>;

		clock-names = "ick";

	};
