[RFC PATCH-for-9.1 07/29] hw/i386/pc: Call fw_cfg_add_extra_pci_roots() in pc_pci_machine_done()

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

fw_cfg_add_extra_pci_roots() expects a PCI bus, which only
PCI-based machines have. No need to call it on the ISA-only
machine. Move it to the PCI-specific machine_done handler.
