Convert the AESNI AVX and AESNI AVX2 implementations of Camellia 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>
