Current description for proximity measurement is ambiguous. While
the first part says that proximity is measured by observing
reflectivity, the second part incorrectly infers that reported values
should behave like a distance.
This is because of AS3935 lightning sensor which uses the proximity
API, while not being a true proximity sensor.
Note this is marked for stable as it accompanies a fix in ABI usage
to the sx9500 driver which would otherwise appear to be correct.
