Surely Google is the only copyright holder on the old file and would be
okay with dual licensing here?

I'd expect a Google person.

Any range of values allowed? ~0 is okay?

I'd say that the driver author should be the maintainer, but if you don't know
who is the maintainer because is not specified you can add Benson and me as
maintainers (as chrome-platform maintainers we take care of this and all cros-ec
related drivers)

From hardware point of view, the port id, is a number from 0 to 255. The typical
usage is have two ports with port id 0 and port id 1.
