pci: teach pci_default_config_write() ROM bar for normal/bridge device .

Browse source 
When updated ROM expantion address of header type 0, it missed
to update mappings.
Add PCI_ROM_ADDRESS check whether to call pci_update_mappings()
Also update pci mapping when PCI_ROM_ADDRESS1 is written for header type 1.

pci_update_mapping() path isn't performance critical,
so call it even independent of header type.
