ACPI: thinkpad-acpi: add DMI-based modalias

Browse source 
Add DMI-based aliases to allow module autoloading on select thinkpads.

The aliases will do nothing unless the dmi-based-module-autoloading.patch
patch from Lennart Poettering <mzxreary@0pointer.de> is applied.  Lennart's
patch has been accepted by greghk and will be merged eventually.
