Add PowerPC vector implementation of SM4
* cipher/Makefile.am: Add 'sm4-ppc.c'.
* cipher/sm4-ppc.c: New.
* cipher/sm4.c (USE_PPC_CRYPTO): New.
(SM4_context): Add 'use_ppc8le' and 'use_ppc9le'.
[USE_PPC_CRYPTO] (_gcry_sm4_ppc8le_crypt_blk1_16)
(_gcry_sm4_ppc9le_crypt_blk1_16, sm4_ppc8le_crypt_blk1_16)
(sm4_ppc9le_crypt_blk1_16): New.
(sm4_setkey) [USE_PPC_CRYPTO]: Set use_ppc8le and use_ppc9le
based on HW features.
(sm4_get_crypt_blk1_16_fn) [USE_PPC_CRYPTO]: Add PowerPC
implementation selection.
