From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Currently to change the firmware one has to update the exported
module firmware string and the major-minor versions used for
verification after load. Consolidate that to a single place
defining correct major and minor versions per platform.
v2: Rebased for KBL.
