Adhemerval Zanella Netto 4c128c7823 aarch64: Add optimized chacha20 
It adds vectorized ChaCha20 implementation based on libgcrypt
cipher/chacha20-aarch64.S.  It is used as default and only
little-endian is supported (BE uses generic code).

As for generic implementation, the last step that XOR with the
input is omited.  The final state register clearing is also
omitted.

On a virtualized Linux on Apple M1 it shows the following
improvements (using formatted bench-arc4random data):
