crypto: talitos - Add support for sha256 and md5 variants

Browse Source 
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.
