!2583 [OLK-5.10] Driver for Zhaoxin AES and SHA algorithm 

Merge Pull Request from: @leoliu-oc 
 
Some Zhaoxin processors come with an integrated crypto engine (so called Zhaoxin ACE, Advanced Cryptography Engine) that provides instructions for very fast cryptographic operations with supported AES algorithms.

(The reason for modifying padlock-sha/aes: padlock-sha/aes are also what we are maintaining. The current patch is to refine it, and the old Ceantaur IDs Family6 CPUs and the newer Centaur IDs Family7 CPUs & Zhaoxin IDs CPUs will use different drivers.)

Include:

Add support for Zhaoxin AES algorithm
Add support for Zhaoxin SHA algorithm
