Now that we have a xenpv bus, do we really need a specific nexus for Xen?
We should be able to use the identify callback of xenpv to create the bus.

The other part of this patch can be merged in the patch #14 "Introduce
xenpv bus and a dummy pvcpu device".

On x86 at least we need the Xen specific nexus, or we will fall back to
use the legacy nexus which is not what we really want.


Oh right, in any case can we use the identify callback of xenpv to add the bus?

With this solution xenpv can add itself no matter FreeBSD use the generic nexus or the nexus Xen, of course with a check if we are running on Xen :).

For instance, on ARM side I don't plan to have a specific Xen nexus.
