sound: Add uclass operations for beeping Some audio codecs such as Intel HDA do not need to use digital data to play sounds, but instead have a way to emit beeps. Add this interface as an option. If the beep interface is not supported, then the sound uclass falls back to the I2S interface. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
