Previously this was tied to a given trip point as a cooling device and used the temperature specified for that trip point. This doesn't work well because the throttling mechanism is not a cooling device in the traditional sense. Instead, allow device trees to specify the throttle temperature in the throttle configuration directly so that the throttle doesn't need to be exposed as a cooling device.
