MIPS: lantiq: add support for xrx200 firmware depending on soc type 

VR9 needs different firmware files for the various phy/soc revisions. Some
boards are ship with older and newer SoC revisions. To be able to boot a single
image on all versions we need to define both firmware files inside the
devicetree.
