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.
