crypto: gcm - Use GHASH library instead of crypto_ahash
Make the "gcm" template access GHASH using the library API instead of
crypto_ahash. This is much simpler and more efficient, especially given
that all GHASH implementations are synchronous and CPU-based anyway.
Note that this allows "ghash" to be removed from the crypto_ahash (and
crypto_shash) API, which a later commit will do.
This mirrors the similar cleanup that was done with POLYVAL.
