Domains are a Linux concept, you have to pick a new domain number for each
struct hw_pci you register.

An unrelated comment: your first "reg" field seems to overlap with part
of your configuration space. Is that intentional?
Also, shouldn't your memory space end on a 256MB boundary, rather than
extend up to 0x50203fff?
