Sync fans based on temp instead of duty

[crawfxrd]

The current implementation syncs all fans to the highest duty.

Replace this with syncing to the highest temperature reported by the sensors.

This will allow independent curves for FAN0 and FAN1 that work as expected based on their actual points.

I highly support this, my darp9 is super hot sometimes, I have to turn on fan manually with Fn + 1 but why can't it do that job?

When I use fan it cools down the laptop such that I can put on my lap & work.

@qnxdev this is unrelated to what you're describing. The darp9 only has a single fan, and this issue is about fan speeds on models with dual fans.
