dm: sound: Use the correct number of channels for sound

At present the 'beep' sound generates a waveform for only one channel even
if two are being used. This means that the beep is twice the frequency it
should be. Correct this by making it a parameter.

The fix in a previous commit was correct for sandbox but not for other
boards.

dm: sound: Create a uclass for sound

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.
