From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Holding a cooling device lock around thermal_governor_update_tz() calls
is not necessary and it may cause lockdep to complain if any governor's
.update_tz() callback attempts to lock a cdev.

For this reason, move the thermal_governor_update_tz() calls in
thermal_bind_cdev_to_trip() and thermal_unbind_cdev_from_trip() from
under the cdev lock.
