Add on/off fan support for the ZyXEL NBG7815. Single CPU cores, cluster CPU temperatures and the Aquantia PHY temperature sensor are monitored. The tmp103 sensor is missing from this patch, and can be added later, when kernel is bumped to 6.x, as it seems to require non-trivial hwmon backporting. Add kmod-phy-aquantia as default package while at it.
Note: this patch has been marked RFT, since temperature values tuning is needed from someone actively using this device in high load conditions. Thanks to robimarko for helping me out.
