Subject: [PATCH 3/4] platform/x86: think-lmi: Correct NVME password handling

NVME passwords identifier have been standardised across the Lenovo
systems and now use udrp and adrp (user and admin level) instead of
unvp and mnvp.

This should apparently be backwards compatible.

Also cleaned up so the index is set to a default of 1 rather than 0
as this just makes more sense (there is no device 0).
