ARM: dts: AM33XX: Add AES data and documentation
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";
+ };
