device tree: add nop_node
We have a qemu internal abstraction layer on FDT. While I'm not fully convinced we need it at all, it's missing the nop_node functionality that we now need on e500. So let's add it and think about the general future of that API later. Signed-off-by: Alexander Graf <agraf@suse.de>
