platform/x86: think-lmi: Correct System password interface

Browse source 
[ Upstream commit 97eef59833 ]

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.
