thermal: Fix examples in DT documentation
There are various issues with the examples in this documentation, some of the DT labels are invalid and one of the macro THERMAL_NO_LIMITS referenced is not available as well. This patch attempts to fix such errors in the documentation. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
