In the corner based voting scheme the major corners (SVS, NOM, TURBO)
are sequential and there is no room for adding any intermediate
corners in-between these major corners.
Add support for a level based voting mechanism where all the levels
are sparsely distributed between [1 - 65535] leaving enough room
to add intermediate levels as per system requirements.
