This seems like something that should be common. There was a hwmon
binding just the other day with temperature set points.

Append units and temperature is a bit redundant. Something like
thermtrip-mC or thermtrip-milliC

You could easily have multiple levels of trip points, so perhaps the
name needs to reflect the action (i.e. shutdown).
