Subject: [PATCH v3 1/4] hwmon: (sch56xx) Autoload modules on platform device creation

Right now, when sch56xx-common has detected a SCH5627/SCH5636
superio chip, the corresponding module is not automatically
loaded.
Fix that by adding the necessary device tables to both modules.

Tested on a Fujitsu Esprimo P720.
