UIO: UIO interface to the SMX Cryptengine

[Resend, apologies, linewrap death >( ]

Implement a UIO interface for the SMX Cryptengine.

The Cryptengine found on the Nias Digital SMX board is best suited for a UIO interface. It is not wired in to the cryptographic API as the engine handles it's own keys, algorithms, everything. All that we know about is that if there's room in the buffer, you can write data to it and when there's data ready, you read it out again.

There isn't necessarily even any direct correlation between data going in and data coming out again, the engine may consume or generate data all on its own.

This driver is for proprietary hardware but we're always told to submit the drivers anyway. So here you are. :-)
