However this broke the vexpress config-bus code, which walks up the device tree to find the first node with an "arm,vexpress,site" property. This gave the wrong result (matching the root node instead of the motherboard node), so broke the clocks and some other devices for VExpress boards. Move the whole node back into its original position. This re-introduces the dtc warning, but is conceptually the right thing to do. The dtc warning seems to be overzealous here, there are discussions on fixing or relaxing this check instead.
