This method is used to determine the name of the irq backend's node in the device tree, so that we can find its phandle (after SLOF may have modified it from the phandle we initially gave it). But, in the two cases the only difference between the node name is the presence of a unit address. Searching for a node name without considering unit address is standard practice for the device tree, and fdt_subnode_offset() will do exactly that, making this method unecessary. While we're there, remove the XICS_NODENAME define. The name "interrupt-controller" is required by PAPR (and IEEE1275), and a bunch of places assume it already.
