crypto: nx - Removing CTR mode from NX driver
CTR hardware implementation does not match with kernel spec causing a counter bug
where just low 8 bytes are used for counter, when should be all 16bytes.
Since we already have other counter modes working according with specs
not worth to keep CTR itself on NX.
