hwmon: (dell-smm) Disable fan support for Dell XPS13 9333

Browse Source 
Calling fan related SMM functions implemented by Dell BIOS firmware on Dell
XPS13 9333 freeze kernel for about 500ms. Until Dell fixes it we need to
disable fan support for Dell XPS13 9333.

Via "force" module param fan support can be enabled.
