arm64: dts: qcom: sc7280: Add sc7280-herobrine-audio-rt5682.dtsi

Audio dtsi for sc7280 boards that using rt5682 headset codec:
1. Add dt nodes for sound card which use I2S playback and record
   through rt5682s and I2S playback through max98357a.
2. Enable lpass cpu node and add pin control and dai-links.
