The only existing caller of thermal_zone_get_num_trips(), which is
rcar_gen3_thermal_probe(), uses this function to check whether or
not the number of trips in the given thermal zone is nonzero.

Because it really only needs to know whether or not the given
thermal zone is tripless, replace thermal_zone_get_num_trips() with
thermal_zone_is_tripless() that can tell rcar_gen3_thermal_probe()
exactly what it needs to know and make it call that function.

No intentional functional impact.
