The idiomatic approach appears to be for individual board vendors
to allocate IDs, you do end up with multiple IDs from multiple
vendors for the same thing.

In general there's not really much standardizaiton for devices,
the bindings that do exist aren't really centrally documented and
the Windows standard is just to have the basic device
registration in the firmware and do all properties based on
quirking based on DMI information.
