powerpc/pci: Add pcibios_disable_device() hook
This adds a hook into the powerpc pci code for pci_disable_device() calls. The
generic code already provides a weak pcibios_disable_device() symbol, so we
just need to provide our own in powerpc and it'll get picked up.
This is passed directly to the phb controller ops, provided one exists.
