Add dummy 2nd port node to rcar_sound ports node to satisfy dtc recommendation that #address-cells / #size-cells is only needed.
This addresses the following warning: arch/arm64/boot/dts/renesas/salvator-common.dtsi:703.8-719.4: Warning (graph_child_address): /soc/sound@ec500000/ports: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary arch/arm64/boot/dts/renesas/salvator-common.dtsi:703.8-719.4: Warning (graph_child_address): /soc/sound@ec500000/ports: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary This change should not have any run-time effect.
