Subject: [PATCH] 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.

-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@...00000 {
-		compatible = "ti,omap4-aes";
-		ti,hwmods = "aes";
-		reg = <0x53500000 0xa0>;
-		interrupts = <102>;
-		dmas = <&edma 6>,
-		       <&edma 5>;
-		dma-names = "tx", "rx";
-	};
