crypto: arm64/ghash - register PMULL variants as separate algos
The arm64 GHASH implementation either uses 8-bit or 64-bit polynomial multiplication instructions, since the latter are faster but not mandatory in the architecture. Since that prevents us from testing both implementations on the same system, let's expose both implementations to the crypto API, with the priorities reflecting that the P64 version is the preferred one if available.
