crypto: gcm - Use GHASH digest algorithm
Remove the dedicated GHASH implementation in GCM, and uses the GHASH digest algorithm instead. This will make GCM uses hardware accelerated GHASH implementation automatically if available. ahash instead of shash interface is used, because some hardware accelerated GHASH implementation needs asynchronous interface.
