vfio/pci: Respond to KVM irqchip change notifier
VFIO PCI devices already respond to the pci intx routing notifier, in order to update kernel irqchip mappings when routing is updated. However this won't handle the case where the irqchip itself is replaced by a different model while retaining the same routing. This case can happen on the pseries machine type due to PAPR feature negotiation. To handle that case, add a handler for the irqchip change notifier, which does much the same thing as the routing notifier, but is unconditional, rather than being a no-op when the routing hasn't changed.
