This option is always selected from LOONGSON_MACH3X.  Switch to just
seleting PCI from that option and definining LOONGSON_PCIIO_BASE based
on CONFIG_LOONGSON_MACH3X.

Should this also select PCI_DOMAINS to preserve the existing behavior?

If not, could you explain why in the commit message?

Thanks,

Ah, I see - PCI already selects PCI_DOMAINS. I think it would have been
worth mentioning but I don't mind if you don't think it a big enough
deal to respin the patch, so:

OK, I added "PCI already selects PCI_DOMAINS"
in the commit description.
