[v2,24/30] PCI/tegra: Remove redundant tegra_pcie_scan_bus()

Commit Message

Now pci_scan_root_bus() is almost simliar to
pci_create_root_bus() + pci_scan_child_bus().
So we could use common pci_scan_root_bus() in
pci_common_init_dev() to scan pci busses.
tegra_pcie_scan_bus() is redundant, remove it.
