Add support for LiPPERT Hurricane-LX (EPIC board with AMD Geode-LX,

CS5536, ITE IT8712F).  Board support is based on the SpaceRunner-LX
(with tiny bits from the RoadRunner-LX) even though the hardware really
was the ancestor of our three other -LX boards and in fact among the
earliest Geode-LX boards on the market.  (Might even have been the first
Geode-LX EPIC?)
