FROMGIT: drivers/thermal/thermal_of: Add change_mode 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 mode change notification from
thermal core.

Add support for change_mode ops in thermal_of interface so that sensor
driver can use this ops for mode change notification.
