Indeed, ACPI thermal zone may have more thermal trip points than the
hwmon interface specifies. Two of the trip points can be mapped to
temp1_max and temp1_crit, respectively. If we want to handle them all,
then probably we have to implement Henrique's suggestion and really
think in terms of thermal zones, i.e. the trip points would be mapped
to temp1_auto_point[1-*]_temp and possibly associated with a fan speed
