PM: Updated Stop API based on modified HOMER layout.

This commit updates the STOP APIs to accomodate changes made in HOMER
layout. CME region begins at an offset of 2MB wrt start of HOMER whereas
STOP GPE regions begins at 1 MB wrt start of HOMER. There are some
corrections for minor coding aesthetics issues.
