In Linux FDT pcie does not have compatible string. Configuration of windows in mv_common was based on fdt compatible. Now pcie windows are configured by their parent: pcie_controller. Processing is moved to fdt_win_process_child. fdt_win_process now only walk through the tree. SOC_NODE_PCI is position of pcie function in soc_node_spec array. PCIe probe cannot use ofw_bus_search_compatible, because it needs to check also device type and parents compatible.
