drivers: thermal: of-thermal: Add support for getting trip temperature 



Add support for the sensor drivers using of-thermal interface to support
reading the trip temperature from the hardware using a callback. This
can be used in case, when the hardware works on a pre-configured
threshold different from the threshold set by software.
