arm64: dts: allwinner: a523: Add SPDIF output PH pin mux option

Browse Source 
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 (gmac0). However, some devices
don't use gmac0 and instead use gmac1 for the only available ethernet
port, leaving the pin free to use for SPDIF.

Add the remaining pin mux option from the PH pin group to the dtsi so
such devices can (later) use it.
