This function is used to update the cooling state of
all the cooling devices that are bound to an active trip point.
This will be used for passive cooling as well, in the future patches.
as both active and passive cooling can share the same algorithm,
which is
1. if the temperature is higher than a trip point,
a. if the trend is THERMAL_TREND_RAISING, use higher cooling
state for this trip point
b. if the trend is THERMAL_TREND_DROPPING, use lower cooling
state for this trip point
2. if the temperature is lower than a trip point, use lower
cooling state for this trip point.
