crypto: talitos - prepare for adding ahash algorithms
No functional changes. Use a union in talitos_alg_template for the crypto_alg so that we can add a member later for ahash_alg. Signed-off-by: Lee Nipper <lee.nipper@gmail.com> Acked-By: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
