platform/x86: think-lmi: Allow empty admin password
SVP = BIOS Supervisor/Admin password SMP = BIOS System password If SMP ACL is enabled in the BIOS then the system allows you to set the SMP without a SVP password configured. Change code to allow this. BIOS will return permissions error if SVP is required.
