[0/2] hw/misc: Model ASPEED hash and crpyto engine

Message

This adds a model for the ASPEED hash and crypto engine (HACE) found on
all supported ASPEED SoCs.

The model uses Qemu's gcrypto API to perform the SHA and MD5 hashing
directly in the machine's emulated memory space, which I found a neat
use of Qemu's features.

It has been tested using u-boot and from Linux userspace.
