Yah, I've seen some of this complexity too..
A thought that crosses my head is to try and leave the entire arch
support intact and build a separate 'domain-driver-based' support
that completely replaces the arch support, a domain would use one or
the other but never both.
So pci_domain_nr could become:
struct pci_domain_driver *drv = pci_get_domain_driver(bus);
if (drv)
return drv->domain_nr;
else
return _arch_pci_domain_nr(bus);
And other funcs would change effectively the same way.

You can probably start with 'of_alias_get_id'..
