camellia: add POWER8/POWER9 vcrypto implementation
* cipher/Makefile.am: Add 'camellia-simd128.h',
'camellia-ppc8le.c' and 'camellia-ppc9le.c'.
* cipher/camellia-glue.c (USE_PPC_CRYPTO): New.
(CAMELLIA_context) [USE_PPC_CRYPTO]: Add 'use_ppc', 'use_ppc8'
and 'use_ppc9'.
[USE_PPC_CRYPTO] (_gcry_camellia_ppc8_encrypt_blk16)
(_gcry_camellia_ppc8_decrypt_blk16, _gcry_camellia_ppc8_keygen)
(_gcry_camellia_ppc9_encrypt_blk16)
(_gcry_camellia_ppc9_decrypt_blk16, _gcry_camellia_ppc9_keygen)
(camellia_ppc_enc_blk16, camellia_ppc_dec_blk16)
(ppc_burn_stack_depth): New.
(camellia_setkey) [USE_PPC_CRYPTO]: Setup 'use_ppc', 'use_ppc8'
and 'use_ppc9' and use PPC key-generation if HWF is available.
(camellia_encrypt_blk1_32)
(camellia_decrypt_blk1_32) [USE_PPC_CRYPTO]: Add 'use_ppc' paths.
(_gcry_camellia_ocb_crypt, _gcry_camellia_ocb_auth): Enable
generic bulk path when USE_PPC_CRYPTO is defined.
* cipher/camellia-ppc8le.c: New.
* cipher/camellia-ppc9le.c: New.
* cipher/camellia-simd128.h: New.
* configure.ac: Add 'camellia-ppc8le.lo' and 'camellia-ppc9le.lo'.
