Log:
  Correct MPIC order of attachment
  
  If MPIC happens to be a slave interrupt controller (as on Armada38x),
  it should be attached after primary interrupt controller.
  Thus BUS_PASS_ORDER_LATE was added to default BUS_PASS_INTERRUPT.
  
  This change doesn't affect the cases when MPIC is standalone IC.
