[ARM] orion5x: add sram support for crypto
The security accelerator which can act as a puppet player for the crypto
engine requires its commands in the sram. This patch adds support for the
phys mapping and creates a platform device for the actual driver.
[ nico: renamed device name from "mv,orion5x-crypto" to "mv_crypto"
so to match the module name and be more generic for Kirkwood use ]
