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. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
