ROG Ally partially supported.

I only tested TDP control and custom fan curves on current SteamOS 3.8 "Main" branch.

TDP control just outright doesn't work while custom fan curves do work but only after toggling "Enable settings" on PowerControl.

@SilverSplinter is this still an Issue for you? SteamOS got some updates since then
