Series allwinner: a523: Enable I2S and SPDIF TX |

Commit Message

The SPDIF hardware block in the A523 SoC has the same layout as the
H616 for the transmitter side. However unlike previous generations,
the hardware block now takes separate module clocks for the TX and RX
sides. This presumably allows the hardware to send and receive audio
streams at different sample rates. The new hardware also gained RX
insertion detection, and some extra information registers.

Add a new compatible for it without any fallbacks.
