thermal: Fix binding problem when there is thermal zone params
The thermal zone params can be used to set governor to specific thermal governor for thermal zone device. But if the thermal zone params has only governor name without thermal bind params, then the thermal zone device will not be binding to cooling device. Because tz->ops->bind operator is not invoked in bind_tz() and bind_cdev() when there is thermal zone params.
