drm/amd/pm: Disable fan control if not supported

Browse source

On Sienna Cichild, not all platforms use PMFW based fan control
(ex: fanless systems). On such ASICs fan control by PMFW will be
disabled in PPTable. Disable hwmon knobs for fan control also as
it is not possible to report or control fan speed on such platforms
through driver.

v3: FeaturesToRun casted as uint64_t
