[ Upstream commit 385e5f57053ff293282fea84c1c27186d53f66e1 ]

A user reported that the program dell-bios-fan-control
worked on his Dell XPS 13 7390 to switch off automatic
fan control.
Since it uses the same mechanism as the dell_smm_hwmon
module, add this model to the fan control whitelist.

Compile-tested only.
