Da7219 and max98357a share the same I2S lines. When writing audio data to the I2S, both codecs generate sound.
Da7219 already has a separate control "Headphone Switch". Adds a new control "Speakers Switch" for turning on/off max98357a. Userspace program can decide to turn on/off which codecs by different use cases.
