Initial support for MSI-X. Only supported on amd64 for now. I have diffs to
actually use this in em(4) and xhci(4), but I'm not committing those yet
because we almost certainly need to save and restore the MSI-X registers
during suspend/resume. However, this allows mpi@ to play with multiple-vector
support in networking hardware.
