+Add the generic AM33XX SHAM 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 SHAM module.

++OMAP SoC SHA crypto Module
++
++Required properties:
++
++- compatible : Should contain entries for this and backward compatible
++ SHAM versions:
++ - "ti,omap2-sham" for OMAP2 & OMAP3.
++ - "ti,omap4-sham" for OMAP4 and AM33XX.
++ Note that these two versions are incompatible.
++- ti,hwmods: Name of the hwmod associated with the SHAM module
++- reg : Offset and length of the register set for the module
++- interrupts : the interrupt-specifier for the SHAM module.
++
++Optional properties:
++- dmas: DMA specifiers for the rx dma. See the DMA client binding,
++ Documentation/devicetree/bindings/dma/dma.txt
++- dma-names: DMA request name. Should be "rx" if a dma is present.
++
++Example:
++ /* AM335x */
++ sham: sham@53100000 {
++ compatible = "ti,omap4-sham";
++ ti,hwmods = "sham";
++ reg = <0x53100000 0x200>;
++ interrupts = <109>;
++ dmas = <&edma 36>;
++ dma-names = "rx";
++ };
