Convert the AVX and AVX2 implementations of Serpent from the (deprecated) ablkcipher and blkcipher interfaces over to the skcipher interface. Note that this includes replacing the use of ablk_helper with crypto_simd. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
