Yeah, looking at this, I think it still fragile. First of all, either this is
missing, or simply wrong. We would need to access indices. ACPI _ADR is in the
specification. As much as with PCI it may be considered reliable.

So, that said, forget about it, and simply use _ADR as indicator of the node.
See how MFD (in the Linux kernel) cares about this. Ex. Diolan DLN-2 driver.

And that said, maybe CP2112 should simply re-use what MFD _already_ provides?
