From: Mohammad Rafi Shaik <mohammad.rafi.shaik@xxxxxxxxxxxxxxxx>
Add the sound card for monaco-evk board and verified playback
functionality using the max98357a I2S speaker amplifier and I2S
microphones. The max98357a speaker amplifier is connected via
High-Speed MI2S HS0 interface, while the microphones utilize the
Secondary MI2S interface and also enable required pin controller
gpios for audio.
