+ Use a faster and more secure NEON based implementation of AES in CBC,

+ Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
+ and for XTS mode encryption, CBC and XTS mode decryption speedup is
+ around 25%. (CBC encryption speed is not affected by this driver.)
+ This implementation does not rely on any lookup tables so it is
