This patch adds the board code to register a per-board au1000-eth
platform device to be used wit the au1000-eth platform driver in a
subsequent patch. Note that the au1000-eth driver knows about the
default driver settings such that we do not need to pass any
platform_data informations in most cases except db1x00.
