crypto: octeontx - Fix sparse warnings

Browse Source 
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.
