[PATCH 4/4] hwmon: (dell-smm) Add support for Dell OptiPlex 7040

[Armin Wolf <W_Armin@gmx.de>]

The Dell OptiPlex 7040 supports the legacy SMM interface for reading
sensors and performing fan control. Whitelist this machine so that
this driver loads automatically.

Closes: https://github.com/Wer-Wolf/i8kutils/issues/15
