crypto: x86/sha256 - implement ->digest for sha256
Implement a ->digest function for sha256-ssse3, sha256-avx, sha256-avx2,
and sha256-ni. This improves the performance of crypto_shash_digest()
with these algorithms by reducing the number of indirect calls that are
made.
For now, don't bother with this for sha224, since sha224 is rarely used.
