AFAICT the idiomatic thing for ACPI would be platform quirks based on
DMI information.  Yay ACPI.  If the system is more Linux targetted then
you can use _DSD properties to store DT properties, these can then be
parsed out in a firmware interface neutral way via the fwnode API.  I'm
not sure there's any avoiding dealing with firmware interface specifics
at some point if we need platform description.

DT does have bindings for devices on discoverable buses like PCI - I
think the original thing was for vendors cheaping out on EEPROMs though
it's also useful when things are soldered down in embedded systems.
