thermal: sysfs: add comments describing locking strategy
The locking strategy of sysfs entries in thermal subsystem
is to hold a lock to serialize access to struct thermal_zone_device
and struct thermal_cooling_device data. Besides, the respective
locks will also be held if calls to ops need to be done to fetch
data or to trigger driver actions.
The exception of the locking strategy are functions called
during initialization of cdev and tz.
