This patch enables the sch56xx-common module to get automatically
loaded on supported machines.
If a machine supports Fujitsu's SCH56XX-based hardware monitoring
solutions, it contains a "Antiope"/" Antiope" dmi onboard device
in case of the sch5627 or a "Theseus"/" Theseus" dmi onboard device
in case of the sch5636.
Since some machines like the Esprimo C700 have a seemingly faulty
DMI table containing both onboard devices, the driver still needs
to probe for the individual superio chip, which in presence of at
least one DMI onboard device however can be considered safe.
Also add a module parameter allowing for bypassing the
DMI check.

Tested on a Fujitsu Esprimo P720.
