crypto: arm64/chacha - depend on generic chacha library instead of crypto driver
Depend on the generic ChaCha library routines instead of pulling in the
generic ChaCha skcipher driver, which is more than we need, and makes
managing the dependencies between the generic library, generic driver,
accelerated library and driver more complicated.
While at it, drop the logic to prefer the scalar code on short inputs.
Turning the NEON on and off is cheap these days, and one major use case
for ChaCha20 is ChaCha20-Poly1305, which is guaranteed to hit the scalar
path upon every invocation (when doing the Poly1305 nonce generation)
