BXT Uses old interpretation.
CNL/ICL+ All(205+)
GLK All(205+)
SKL All PV releases (Check for 205+ might help but cannot be foolproof)

v2: Jani
    Keep the bdb version check.
v3:
    Apply newer version for skl from 205+(DK).
    Add (version check && platform list) (Jani).
    Add bdb version for each platform in commit message(DK).
