Primary, secondary and subordinate default bus numbers are 0 in Tegra and it is expecting SW to program these numbers in configration space. pci_scan_bridge_extend() function programs these numbers in configuration space if secondary & subordinate bus numbers are 0 or PCI_REASSIGN_ALL_BUS flag is set. Since secondary & subordinate default bus numbers are 0, PCI_REASSIGN_ALL_BUS flag can be removed for Tegra PCIe.
