ARM: dts: meson8m2: m8s: enable the audio outputs - WiP 



The M8S board uses an Everest Semi ES7134 I2S stereo codec which is
connected to GPIOAO_8..11. SPDIF output is connected through GPIOY_3.

WIP:
- depends on previous commits (audio driver and bindings not finalized)
- doesn't seem to work?
