* cipher/rijndael-internal.c (USE_S390X_CRYPTO): New.
(RIJNDAEL_context_s) [USE_S390X_CRYPTO]: New 'km*_func' members.
* cipher/rijndael-s390x.c: New.
* cipher/rijndael.c (_gcry_aes_s390x_setup_acceleration)
(_gcry_aes_s390x_setup_setkey)
(_gcry_aes_s390x_setup_prepare_decryption, _gcry_aes_s390x_encrypt)
(_gcry_aes_s390x_decrypt): New.
(do_setkey) [USE_S390X_CRYPTO]: Add s390x acceleration setup.

Patchs adds acceleration for single-block AES and following modes:
- CBC, CBC-MAC, CFB, OFB, CTR, XTS and OCB
