From: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

commit fbddf68d7b4e1e6da7a78dd7fbd8ec376536584a upstream.

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")
