Revert "crypto: blowfish - add AVX2/x86_64 implementation of blowfish cipher"
This reverts commit 604880107010a1e5794552d184cd5471ea31b973. 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".
