The "isapc" machine only provides an ISA bus, not a PCI one,
and doesn't instanciate any i440FX south bridge.
Its machine class defines PCMachineClass::pci_enabled = false,
and pc_init1() only uses the pci_type argument when pci_enabled
is true. Since for this machine the argument is not used,
passing NULL makes more sense.
