dm: sound: Create a uclass for i2s The i2s bus is commonly used with audio codecs. It provides a way to stream digital data sychronously in both directions. U-Boot only supports audio output, so this uclass is very simple, with a single tx_data() method. Add a uclass and a test for i2s. Signed-off-by: Simon Glass <sjg@chromium.org>
