This is a straight port to arm64/NEON of the x86 SSE3 implementation
of the ChaCha20 stream cipher. It uses the new skcipher walksize
attribute to process the input in strides of 4x the block size.

This patch reverts the following commits:
8621caa0d48096667273
I should not have applied them because they had already been
obsoleted by a subsequent patch series. They also cause a build
failure because of the subsequent commit 9ae433bc79.
Fixes: 9ae433bc79 ("crypto: chacha20 - convert generic and...")
