Add an active state for automatic fan control

Each zone contains an active state that determines whether the
automatic fan control algorithm is active and controlling the fan speeds
dynamically or not.

This will be used to determine if the fan speeds within the zone are set
dynamically or rather held at another speed for a determined reason.
