    platform/x86: think-lmi: Correct System password interface
    
    [ Upstream commit 97eef5983372d7aee6549d644d788fd0c10d2b6e ]
    
    The system password identification was incorrect. This means that if
    the password was enabled it wouldn't be detected correctly; and setting
    it would not work.
    Also updated code to use TLMI_SMP_PWD instead of TLMI_SYS_PWD to be in
    sync with Lenovo documentation.
