  Drivers:
   - Add NEON acclerated chacha20 on ARM/ARM64
   - Expose AES-CTR as synchronous skcipher on ARM64
   - Add scalar AES implementation on ARM64
   - Improve scalar AES implementation on ARM
   - Improve NEON AES implementation on ARM/ARM64
   - Merge CRC32 and PMULL instruction based drivers on ARM64
   - Add NEON acclerated CBCMAC/CMAC/XCBC AES on ARM64
   - Add IPsec AUTHENC implementation in atmel
   - Add Support for Octeon-tx CPT Engine
   - Add Broadcom SPU driver
