9e1fec4d78 emulation: update offset of xous.img 
This image file should get loaded onto SPI flash rather than into RAM,
since RAM gets cleared by the bootloader now.

Place it at a location that matches real hardware.

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.

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.
