Merge branch 'thermal-core'

Merge thermal core updates for 6.12 which, among other things, rework
the thermal driver interface for binding cooling devices to thermal
zones and add a thermal core testing module:

 - Update some thermal drivers to eliminate thermal_zone_get_trip()
   calls from them and get rid of that function (Rafael Wysocki).

 - Update the thermal sysfs code to store trip point attributes in trip
   descriptors and get to trip points via attribute pointers (Rafael
   Wysocki).

 - Move the computation of the low and high boundaries for
   thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
   Lezcano).

 - Introduce a debugfs-based facility for thermal core testing (Rafael
   Wysocki).

 - Replace the thermal zone .bind() and .unbind() callbacks for binding
   cooling devices to thermal zones with one .should_bind() callback
   used for deciding whether or not a given cooling devices should be
   bound to a given trip point in a given thermal zone (Rafael Wysocki).

 - Eliminate code that has no more users after the other changes, drop
   some redundant checks from the thermal core and clean it up (Rafael
   Wysocki).

 - Fix rounding of delay jiffies in the thermal core (Rafael Wysocki).
