dt-bindings: gpu: Convert Samsung Image Rotator to dt-schema

* Samsung Image Rotator

Required properties:

  - compatible : value should be one of the following:

	* "samsung,s5pv210-rotator" for Rotator IP in S5PV210

	* "samsung,exynos4210-rotator" for Rotator IP in Exynos4210

	* "samsung,exynos4212-rotator" for Rotator IP in Exynos4212/4412

	* "samsung,exynos5250-rotator" for Rotator IP in Exynos5250

  - reg : Physical base address of the IP registers and length of memory

	  mapped region.

  - interrupts : Interrupt specifier for rotator interrupt, according to format

		 specific to interrupt parent.

  - clocks : Clock specifier for rotator clock, according to generic clock

	     bindings. (See Documentation/devicetree/bindings/clock/exynos*.txt)

  - clock-names : Names of clocks. For exynos rotator, it should be "rotator".

Example:

	rotator@12810000 {

		compatible = "samsung,exynos4210-rotator";

		reg = <0x12810000 0x1000>;

		interrupts = <0 83 0>;

		clocks = <&clock 278>;

		clock-names = "rotator";

	};
