From: Mohammad Rafi Shaik <redacted> Add the sound card for Lemans-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 HS2 interface. This patch also introduces pin control support for the High-Speed I2S interfaces.
