You can describe the offset and slope using DT and avoid this to be hard
coded in your driver. Besides, if you read offset and slope from DT,
your driver will be ready for any upcoming sensor addition that you may
want to support in future, given that would required slope and offset
change, per sensor, per chip version.

Can you please check if you can move these to DT?
