ARM: dts: ixp4xx: Add devicetree for D-Link DSM-G600 rev A
This adds a devicetree for the D-Link DSM-G600 Wireless Network Storage Enclosure so that we can delete the boardfile. The boardfile does not even define an ethernet interface as it has an external ethernet on PCI. This devicetree is for revision A using IXP420 the rev B version uses PowerPC.
