Thermal: Add start and stop operations in thermal_governor structure
Added start and stop operations to initialize and uninitialize governor
in thermal_governor structure.
The start and stop operations will be called when thermal zone is registered
and when change governor via sysfs. They will be not called when cooling
devices are registered or when cooling devices are bound to thermal zones.
