d248ab3cc7 emulation: engine: always update registers on write 
These registers get reset when the hardware is reset, however the engine
may still be running. Ensure it's not running when the device is reset.

3f1593e56e emulation: engines: cache registers in RAM 
Don't consult RAM every time we want to read a register. This improves
performance at the cost of potentially having stale registers.

50c5e1290d memlcd: implement vram 
Now that peripherals handle memory themselves, we need a special block
to handle video memory.

5ae1e437ab sha512: fix length and 512/256 calculation 
The length is now correctly calculated, and the engine properly
completes.

Additionally, a bulk 512/256 implementation has been written that works
well enough, but will fall over if asked to compute a large amount of
data.
