platform/x86: think-lmi: Opcode support
Implement Opcode support.
This is available on ThinkCenter and ThinkStations platforms and
gives improved password setting capabilities
Add options to configure System, HDD & NVMe passwords.
HDD & NVMe passwords need a user level (user/master) along with
drive index.
