There's no such module option, what's wrong with a script?  Part of the
reason we don't have such a module option is that PCI addresses are not
persistent, they can change based on devices added or removed, or even
motherboard BIOS updates.  Userspace has more flexibility for managing
this and is fully able to do so via initrd scripts and modprobe.d.
