x86/PCI: Use pcibios_scan_root() instead of pci_scan_bus_with_sysdata()
pci_scan_bus_with_sysdata() and pcibios_scan_root() are quite similar: pci_scan_bus_with_sysdata pci_scan_bus_on_node(..., &pci_root_ops, -1) pcibios_scan_root pci_scan_bus_on_node(..., &pci_root_ops, get_mp_bus_to_node(busnum)) get_mp_bus_to_node() returns -1 if it couldn't find the node number, so this removes pci_scan_bus_with_sysdata() and uses pcibios_scan_root() instead.
