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

Browse Source 
This reverts commit 6048801070.

Instruction (vpgatherdd) that this implementation relied on turned out to be
slow performer on real hardware (i5-4570). The previous 4-way blowfish
implementation is therefore faster and this implementation should be removed.

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".
