Anson Huang 2afca9456e thermal: Add generic device cooling support
To compatible with previous implementation, add generic device
cooling support, each thermal zone will register a cooling
device, and when temperature exceed passive trip, the device
cooling driver will send out a system wide notification, each
device supporting cooling will need to register device cooling
and takes action when passive trip is exceeded;
