crypto: qce - Add support for AEAD algorithms

Browse Source 
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))
