MIPS/PCI: Implement pcibios_get_phb_of_node



The of_node field of the device assigned to a
PCI bus is used during scanning of the PCI bus.
However on MIPS, the of_node field is assigned
only after the bus has been scanned.

Implement the architecture specific version of
'pcibios_get_phb_of_node'. Which ensures that the
PCI driver core will initialize the of_node field
before starting the scan.

Also remove the local assignment of bus->dev.of_node,
it is not needed after the patch.
