What about something like:

sensor-coefficients = <x1 y1 z1>,
                                  <x2 y2 z2>,
                                  ...;

Where in general `x` is the sensor-id, `y` the slope and `z` the
offset for the sensor reading.
So the reported reading to hwmon (and thermal for temperature) for
sensor with id `x1` is `y1 * val + z1`, the same for sensor with id x2
and so on for all the sensors in the array.
