ASoC: cs53l30: Add MUTE pin control support via GPIO
The codec chip has a physical MUTE pin to let users control it via GPIO. So this patch add a mute control support to the driver. Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Acked-by: Paul Handrigan <Paul.Handrigan@cirrus.com> Signed-off-by: Mark Brown <broonie@kernel.org>
