[PATCH] s390: des crypto code speedup

Provide ECB and CBC encrypt / decrypt functions to crypto API to speed up our
hardware accelerated DES implementation.  This new functions allow the crypto
API to call ECB / CBC directly with large blocks in difference to the old
functions that were calles with algorithm block size (8 bytes for DES).

This is up to factor 10 faster than our old hardware implementation :)
