Log:
  MFC r247279
  
  The 5300 series ciss(4) board does not work in performant mode with our
  currnet initialization sequence.  Set it to simple mode only so that
  systems can be updated from stable/7 to newer installations.
  
  At some point, we should figure out why we cannot initialize performant
  mode on this board.
