+Add the generic AM33XX AES module's device tree data and
+enable it for the am335x-evm, am335x-evmsk, and am335x-bone
+platforms. Also add Documentation file describing the data
+for the AES module.

++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";
++ };
