[PATCH 5/6] hw: Use pci_bus_add_fw_cfg_extra_pci_roots()

[Philippe Mathieu-Daudé]

We want to remove fw_cfg_add_extra_pci_roots() which introduced
PCI bus knowledge within the generic hw/nvram/fw_cfg.c file.
Replace the calls by the pci_bus_add_fw_cfg_extra_pci_roots()
which is a 1:1 equivalent, but using correct API.
