If nth bit is set, then the cdev and thermal zone are bound
for trip point n.
+ .limits: This is an array of cooling state limits. Must have exactly
+ 2 * thermal_zone.number_of_trip_points. It is an array consisting
+ of tuples <lower-state upper-state> of state limits. Each trip
+ will be associated with one state limit tuple when binding.

.match: This call back returns success(0) if the 'tz and cdev' need to
be bound, as per platform data.
