Thermal control fixes for 6.10-rc4

 - Prevent the thermal core from failing the registration of a cooling
   device if its .get_cur_state() reports an incorrect state to start
   with which may happen for fans handled through firmware-supplied AML
   in ACPI tables (Rafael Wysocki).

 - Make the ACPI thermal zone driver initialize all trip points with
   temperature of 0 centigrade and below as invalid because such trip
   point temperatures do not make sense on systems with ACPI thermal
   control and they cause performance regressions due to permanent
   thermal mitigations to occur (Rafael Wysocki).

 - Restore passive polling management in the Step-Wise thermal governor
   that uses it to ensure that all cooling devices used for thermal
   mitigation will go back to their initial states eventually (Rafael
   Wysocki).
