Put the struct definitions for AES keys and the asm function prototypes in a
separate header and export the asm functions from the module.
This allows other drivers to use them directly.

Add assembler versions of AES and SHA1 for ARM platforms. This has provided
up to a 50% improvement in IPsec/TCP throughout for tunnels using AES128/SHA1.
