platform/x86: think-lmi: add missing type attribute
This driver was missing the mandatory type attribute...oops.
Add it in along with logic to determine whether the attribute is an
enumeration type or a string by parsing the possible_values attribute.
Upstream bug https://bugzilla.kernel.org/show_bug.cgi?id=216460
Fixes: a40cd7ef22fb ("platform/x86: think-lmi: Add WMI interface support on Lenovo platforms")
