MLK-12312: CAAM hash algorithms fail registration during initialization

Fix cherry-picked from 5ec908319a

crypto: caam - only export the state we really need to export

Avoid exporting lots of state by only exporting what we really require,
which is the buffer containing the set of pending bytes to be hashed,
number of pending bytes, the context buffer, and the function pointer
state.  This reduces down the exported state size to 216 bytes from
576 bytes.
