thermal: core: Introduce thermal_trip_crossed()
Add a helper function called thermal_trip_crossed() to be invoked by __thermal_zone_device_update() in order to notify user space, the thermal debug code and the zone governor about trip crossing. Subsequently, this will also be used in the case when a trip point becomes invalid after being crossed on the way up. No intentional functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
