crypto: sha256 - Add sha224 support to sha256 library code
Add sha224 support to the lib/crypto/sha256 library code. This will allow us to replace both the sha256 and sha224 parts of crypto/sha256_generic.c when we remove the code duplication in further patches in this series. Suggested-by: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
