dt-bindings: hwmon: lm90: add ti,extended-range-enable property
Some devices can operate in an extended temperature mode. Therefore add a boolean ti,extended-range-enable to be able to select this feature in the device tree node. Also make sure that this feature can only be enabled for the devices supporting this feature.
