hw: Model ASPEED's Hash and Crypto Engine
The HACE (Hash and Crypto Engine) is a device that offloads MD5, SHA1, SHA2, RSA and other cryptographic algorithms. This initial model implements a subset of the device's functionality; currently only MD5/SHA hashing, and on the ast2600's scatter gather engine.
