crypto: qce - Add support for AEAD algorithms

Introduce support to enable following algorithms in Qualcomm Crypto Engine. - authenc(hmac(sha1),cbc(des)) - authenc(hmac(sha1),cbc(des3_ede)) - authenc(hmac(sha256),cbc(des)) - authenc(hmac(sha256),cbc(des3_ede)) - authenc(hmac(sha256),cbc(aes)) - ccm(aes) - rfc4309(ccm(aes)) Signed-off-by: Thara Gopinath <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
