FROMLIST: drivers/thermal/thermal_of: Add critical/hot ops support for thermal_of sensor

Browse Source 
The sensor driver which register through thermal_of interface doesn't
have an option to get thermal zone critical, hot trip violation
notification from thermal core.

Add support for these ops in thermal_of interface so that sensor
driver can use these ops.
