    baytrail: initialize punit
    
    The punit is responsible for a number of things. Without
    performing the sequence included it won't change processor
    frequency when requested and apparently there are some bizarre
    hangs introduced if this sequence isn't included either. Lastly,
    this needs to come after microcode has been loaded. As that is
    done in bootblock the ordering is correct.
    
    One other side effect is that this fixes the graphics devices'
    device id. Before it was showing up as the same device id of the
    SoC transaction router.
