PCI: deprecate pci_scan_bus_parented() 



Users of pci_scan_bus_parented() should be converted to use either
    pci_scan_root_bus() (preferred, but also calls pci_bus_add_devices)
or
    pci_create_root_bus()
    pci_scan_child_bus()

Since pci_scan_bus_parented(), I'm marking it deprecated now and will
actually remove it later.

What:	pci_scan_bus_parented()

When:	3.5

Why:	The pci_scan_bus_parented() interface creates a new root bus.  The

	bus is created with default resources (ioport_resource and

	iomem_resource) that are always wrong, so we rely on arch code to

	correct them later.  Callers of pci_scan_bus_parented() should

	convert to using pci_scan_root_bus() so they can supply a list of

	bus resources when the bus is created.
