thermal: Use THERMAL_TREND_{RISING|FALLING} to indicate thermal trends
Values used previously - THERMAL_TREND_{RAISE|DROP}_FULL caused thermal
governor to use the maximal cooling state just after crossing
the first trip point. Such behavior is not acceptable since it causes
the full speed of FAN which is noisy and not really necessary.
With proposed values the fan speed limit is adjusted accordingly.
