crypto: vmx - ghash: do nosimd fallback manually
VMX ghash was using a fallback that did not support interleaving simd and nosimd operations, leading to failures in the extended test suite. If I understood correctly, Eric's suggestion was to use the same data format that the generic code uses, allowing us to call into it with the same contexts. I wasn't able to get that to work - I think there's a very different key structure and data layout being used. So instead steal the arm64 approach and perform the fallback operations directly if required.
