[CRYPTO] geode: Fix in-place operations and set key

Allow in-place crypto operations.  Also remove the coherent user flag
(we use it automagically now), and by default use the user written
key rather then the HW hidden key - this makes crypto just work without
any special considerations, and thats OK, since its our only usage
model.
