nv-public: add support for thermal trip event

Browse Source 
This change binds thermal trip event cooling devices to the following
events:
- sw throttling event
- hot surface event

When the bound trip point temperature gets crossed, the associated
cooling device will become active, and its state can be learnt from the
user space to take the action accordingly.

The thermal trip event cooling device is not needed for safety IGX so
disable it.
