This adds cleanup counterparts to pci_register_root_bus(),
pci_root_bus_new(), and pci_bus_irqs().
These cleanup routines are needed in the case of hotpluggable
PCIHostBridge implementations. Currently we can rely on the
object_unparent()'ing of the PCIHostState recursively unparenting
and cleaning up it's child buses, but we need explicit calls
to also:
1) remove the PCIHostState from pci_host_bridges global list.
otherwise, we risk accessing freed memory when we access
the list later
2) clean up memory allocated in pci_bus_irqs()
Both are handled outside the context of any particular bus or
host bridge's init/realize functions, making it difficult to
avoid the need for explicit cleanup functions without remodeling
how PCIHostBridges are created. So keep it simple and just add
them for now.
