PCI: tegra: Remove tegra_pcie_scan_bus()
After b97ea289cf6a ("PCI: Assign resources before drivers claim devices (pci_scan_root_bus())"), pci_scan_root_bus() no longer adds the devices, so it is equivalent to tegra_pcie_scan_bus(). Remove tegra_pcie_scan_bus() (the hw.scan method), so we use the generic pci_scan_root_bus() path.
