Joel Stanley acd9575e59 aspeed_scu: Implement RNG register 
The ASPEED SoCs contain a single register that returns random data when
read. This models that register so that guests can use it.

The random number data register has a corresponding control register,
however it returns data regardless of the state of the enabled bit, so
the model follows this behaviour.

When the qcrypto call fails we exit as the guest uses the random number
device to feed it's entropy pool, which is used for cryptographic
purposes.
