drm/nouveau/therm: add support for fan-control modes
For now, only 2 control modes are available: - NONE: The fan is never touched (default) - MANUAL: The fan is set to the user-defined fan speed (pwm1) This patch introduces a distinction between ptherm internal fan management and external fan management. The latter is bound to respect the fan mode while the first can still select the speed it wants unless the NONE mode is selected. This is important for automatic fan management.
