ARM: dts: AM33XX: Add SHAM data and documentation

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 */

compatible = "ti,omap4-sham";
ti,hwmods = "sham";
reg = <0x53100000 0x200>;
