crypto: talitos - Add support for sha256 and md5 variants
This patch adds support for: authenc(hmac(sha256),cbc(aes)), authenc(hmac(sha256),cbc(des3_ede)), authenc(hmac(md5),cbc(aes)), authenc(hmac(md5),cbc(des3_ede)). Some constant usage was changed to use aes, des, and sha include files. Signed-off-by: Lee Nipper <lee.nipper@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
