So, please, put mapping tables into the ACPI or similar

ACPI added _PLD (Physical Device Location) back in 3.0, ISTR.
However, searching my archives, I have yet to see a single instance
of its use in the field.

ACPI also supplies the slot number stuff, which is exported via 
the existing pci_slot driver.
