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.

Impact: Low or Medium
Rationale: Most boards use the same table for both fans. In those cases, there will be no perceived change in behavior to the user. On boards that use a different table for each fan, the different in behavior and between fans may be perceivable to the user. (Looking at existing fan points, oryp9/10 will be the most significant.)

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.

So shall I raise another issue for this?

@swisscdn No need. User-customizable fan curves are already in the works.
