Disable HDMI audio simple-audio-card node as a workaround, since we did not
have the document and not figure out how to set the HDMI audio parameters
for the BBB target board, to avoid below booting error information if
connecting HDMI monitor:
davinci-mcasp.0-i2s-hifi: ASoC: error at __soc_pcm_hw_params on
davinci-mcasp.0-i2s-hifi: -22
davinci-mcasp 48038000.mcasp: stream has more channels (2) than are enabled in
mcasp (0)
davinci-mcasp 48038000.mcasp: ASoC: error at snd_soc_dai_hw_params on
48038000.mcasp: -22
