dt-bindings: hwmon: national,lm90: Fix channel constraints for temperature offset
Limit temperature-offset-millicelsius to remote channels only, since
channel 0 is local and this property does not apply to it.
Channel 2 is only valid on devices with two remote sensors, so reject
channel 2 for compatibles that do not support a second remote channel.
