PCI: tegra: Remove tegra_pcie_scan_bus()

Browse Source 
After b97ea289cf ("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.
