crypto: blowfish - add AVX2/x86_64 implementation of blowfish cipher 

Patch adds AVX2/x86-64 implementation of Blowfish cipher, requiring 32 parallel
blocks for input (256 bytes). Table look-ups are performed using vpgatherdd
instruction directly from vector registers and thus should be faster than
earlier implementations.

Blowfish cipher algorithm (x86_64/AVX2), by Bruce Schneier.
This is a variable key length cipher which can use keys from 32
bits to 448 bits in length. It's fast, simple and specifically
designed for use on "large microprocessors".
