Move PCI device setup from pcibios_add_device() and pcibios_fixup_bus() to

requirement for IOMMU group assignment to work
This fixes IOMMU group assignment for hotplugged devices on pseries, where
the existing behavior results in IOMMU assignment before registration.
Although this is a correct approach which we should proceed with, this
breaks adding of SRIOV VFs from pnv_tce_iommu_bus_notifier (and possibly
the bare metal PCI hotplug), I am trying to fix that now...
Were you able to make any progress? I can think of a couple of ways
to fix SRIOV, but they're not particularly elegant and involve
duplication.
