Configuration for dom0less domUs is stored under /chosen/<domu> nodes present in the host device tree provided to Xen. All the properties and sub nodes there are meant only for Xen. However, at the moment we still copy them (except for modules that we skip) into hardware domain /chosen node. Fix it by adding "xen,domain" compatible into the list of nodes to skip in handle_node().
