Zhang Rui 601f3d4242 Thermal: Introduce .get_trend() callback. ... According to ACPI spec, tc1 and tc2 are used by OSPM to anticipate the temperature trends. We introduced the same concept to the generic thermal layer for passive cooling, but now it seems that these values are hard to be used on other platforms. So We introduce .get_trend() as a more general solution. For the platform thermal drivers that have their own way to anticipate the temperature trends, they should provide their own .get_trend() callback. Or else, we will calculate the temperature trends by simply comparing the current temperature and the cached previous temperature reading.
