x86/PCI: Merge pci_scan_bus_on_node() into pcibios_scan_root()
pci_scan_bus_on_node() is only called by pcibios_scan_root(). This merges pci_scan_bus_on_node() into pcibios_scan_root() and removes pci_scan_bus_on_node(). Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
