The intent of the string was to have the domain number so that
resources in /proc/iomem can be correlated with lspci.

This would be a 'best practice' - all PCI drivers need to request
resource, and the resource should be relatable back to the PCI
domain... So it would be best if the domain number was available at
this point in a driver's flow.

I'm not sure what 'nr' is in this context, if it is not the domain
number then I'd just drop the 0x04x entirely rather than include
some nonsense number...
