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().
