crypto: ahash - Convert to new style algorithms
This patch converts crypto_ahash to the new style. The old ahash algorithm type is retained until the existing ahash implementations are also converted. All ahash users will automatically get the new crypto_ahash type. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>hifive-unleashed-5.1
