the different fan speeds possible. Cooling states are referred to by
single unsigned integers, where larger numbers mean greater heat
dissipation. The precise set of cooling states associated with a device
-(as referred to by the cooling-min-level and cooling-max-level
-properties) should be defined in a particular device's binding.
