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
+- interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this module.
+- interrupts : the interrupt number for the SHAM module.
+
+Optional properties:
+- dmas: DMA specifier 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 at 53100000 {
+ compatible = "ti,omap4-sham";
+ ti,hwmods = "sham";
+ reg = <0x53100000 0x200>;
+ interrupt-parent = <&intc>;
+ interrupts = <109>;
+ dmas = <&edma 36>;
