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.
