rS310776: The JZ4780 I2S can feed either the internal audio codec or the HDMI
Summary

The JZ4780 I2S can feed either the internal audio codec or the HDMI TX, but not both at the same time. With this patch:

  • Add a dev.pcm.0.internal_codec sysctl node for selecting between internal and external codec
  • Changes playback sample rate from 96kHz to 48kHz for HDMI compatibility
  • Enable i2s clock on codec access
