Subject: spapr_pci: Remove finish_realize hook

Now that spapr-pci-vfio-host-bridge is reduced to just a stub, there is
only one implementation of the finish_realize hook in sPAPRPHBClass.  So,
we can fold that implementation into its (single) caller, and remove the
hook.  That's the last thing left in sPAPRPHBClass, so that can go away as
well.
