dt-bindings: crypto: Convert ti,omap4-des to DT schema 



Convert the TI OMAP DES binding to DT schema format.

Drop "ti,hwmods" as it is not actually used for this binding. Only
OMAP2 platforms are using it.

OMAP SoC DES crypto Module



Required properties:



- compatible : Should contain "ti,omap4-des"

- ti,hwmods: Name of the hwmod associated with the DES module

- reg : Offset and length of the register set for the module

- interrupts : the interrupt-specifier for the DES module

- clocks : A phandle to the functional clock node of the DES module

           corresponding to each entry in clock-names

- clock-names : Name of the functional clock, should be "fck"



Optional properties:

- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,

	Documentation/devicetree/bindings/dma/dma.txt

	Each entry corresponds to an entry in dma-names

- dma-names: DMA request names should include "tx" and "rx" if present



Example:

	/* DRA7xx SoC */

	des: des@480a5000 {

		compatible = "ti,omap4-des";

		ti,hwmods = "des";

		reg = <0x480a5000 0xa0>;

		interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;

		dmas = <&sdma 117>, <&sdma 116>;

		dma-names = "tx", "rx";

		clocks = <&l3_iclk_div>;

		clock-names = "fck";

	};
