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

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
