sconfig: rename pci_domain -> domain

The name pci_domain was a bit misleading, since the construct is only
PCI specific in a particular (northbridge/cpu) implementation, but not
by concept. As implementations and hardware change, be more generic
about our naming. This will allow us to support non-PCI systems without
adding new keywords.
