ASoC: cs47l24: Add support for audio trace firmware
cs47l24 supports the audio trace firmware, this streams of audio to be captured from the CODEC over a compressed audio channel for analysis/debugging of audio processing firmwares. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
