thermal: of: Extend current of-thermal.c code to allow setting emulated temp
Before this change it was only possible to set get_temp() and get_trend() methods to be used in the common code handling passing parameters via device tree to "cpu-thermal" CPU thermal zone device. Now it is possible to also set emulated value of temperature for debug purposes.
