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.
