Sure, but having an incomplete file in the kernel is poorly useful, if
not misleading. What about any of these options:

- add to property-units.txt the missing units
- delete property-units.txt from the kernel sources
- replace the entire content of property-units.txt with a link to the
  schema file, stating it is the authoritative and complete source

I would feel a lot better with any of these. I can prepare the patch too.
