crypto: octeontx - Fix sparse warnings
This patch fixes all the sparse warnings in the octeontx driver.
Some of these are just trivial type changes.
However, some of the changes are non-trivial on little-endian hosts.
Obviously the driver appears to be broken on either LE or BE as it
was doing different things. I've taken the BE behaviour as the
correct one.
