[net-next] net: mvneta: Only disable mvneta_bm for 64-bits

Actually only the mvneta_bm support is not 64-bits compatible.
The mvneta code itself can run on 64-bits architecture.

No it cannot, it emits warnings because it casts pointers to and
from 32-bit integers.

I'm not applying this.

Indeed!

There was a missing patch for it that I had in my tree and I didn't
submit yet. I am bout to doing it now.

Thanks,
