ASoC: es8328: Add support for slave mode
Currently, the function that changes the DAI format only supports master mode. Trying to use a slave mode exits the function with -EINVAL and leave the codec misconfigured. This commits adds support for enabling the slave mode. Signed-off-by: Romain Perier <romain.perier@collabora.com> Signed-off-by: Mark Brown <broonie@kernel.org>
