dt-bindings: crypto: Convert ti,omap2-aes to DT schema 



Convert the TI OMAP AES binding to DT schema format. It's a straight
forward conversion.

Make "ti,hwmods" not required as it is deprecated and only used on
OMAP2.

OMAP SoC AES crypto Module



Required properties:



- compatible : Should contain entries for this and backward compatible

  AES versions:

  - "ti,omap2-aes" for OMAP2.

  - "ti,omap3-aes" for OMAP3.

  - "ti,omap4-aes" for OMAP4 and AM33XX.

  Note that the OMAP2 and 3 versions are compatible (OMAP3 supports

  more algorithms) but they are incompatible with OMAP4.

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

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

- interrupts : the interrupt-specifier for the AES module.



Optional properties:

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

	Documentation/devicetree/bindings/dma/dma.txt

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



Example:

	/* AM335x */

	aes: aes@53500000 {

		compatible = "ti,omap4-aes";

		ti,hwmods = "aes";

		reg = <0x53500000 0xa0>;

		interrupts = <102>;

		dmas = <&edma 6>,

		       <&edma 5>;

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

	};
