On qcs9075-iq-evk boards the enable gpios and vref-spply is always on. Not configurable from DT.

Add the sound card node with tested playback over max98357a I2S speakers amplifier and I2S mic. Introduce HS (High-Speed) MI2S pin control support. The I2S max98357a speaker amplifier is connected via HS0 and I2S microphones utilize the HS2 interface.
