The sound driver pulls together the audio codec and i2s drivers in order to actually make sounds. It supports setup() and play() methods. The sound_find_codec_i2s() function allows locating the linked codec and i2s devices. They can be referred to from uclass-private data.
Add a uclass and a test for sound.
