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.

AES interrupts were previously not used, but after recent changes to omap-aes
driver, its being used. We correct the interrupt number to have working PIO
mode.
