crypto: s390/des - convert to skcipher API
Convert the glue code for the S390 CPACF implementations of DES-ECB,
DES-CBC, DES-CTR, 3DES-ECB, 3DES-CBC, and 3DES-CTR from the deprecated
"blkcipher" API to the "skcipher" API. This is needed in order for the
blkcipher API to be removed.
Note: I made CTR use the same function for encryption and decryption,
since CTR encryption and decryption are identical.
