When spdif support was added for the Allwinner A523 family of SoCs, only
two of the three possible pins were added to the dtsi, since the third
would clash with the first ethernet port (emac0)
However, some devices don't use emac0 and instead use emac1 for the only
available ethernet port, leaving the pin free to use for spdif.

Add the missing pin to the dtsi so such devices can (later) use it
