crypto: talitos - add sha224, sha384 and sha512 to existing AEAD algorithms
With this, now all combinations of CBC: AES, 3DES-EDE with HMAC: SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 are supported. Signed-off-by: Horia Geanta <horia.geanta@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
