Subject: [PATCH 1/1] platform/x86: think-lmi: Convert container_of() macros to static inline

The macros to_tlmi_pwd_setting() and to_tlmi_attr_setting() are fragile
because they expect the variable name to be 'kobj', otherwise the build
will fail because container_of()'s 3rd parameter (member) is taken from
the parameter given to the macro.

While at it, move them into a more logical place.
