[PATCH v2] platform/x86: ISST: Correct locked bit width

[Srinivas Pandruvada]

SST-PP locked bit width is set to three bits. It should be only one bit.
Use SST_PP_LOCK_WIDTH define instead of SST_PP_LEVEL_WIDTH.

Fixes: ea009e4769fa ("platform/x86: ISST: Add SST-PP support via TPMI")

Thank you for your contribution, it has been applied to my local
fixes branch. Note it will show up in the public
platform-drivers-x86/fixes branch only once I've pushed my
local branch there, which might take a while.
