ASoC: rsnd: add workaround for SRC sync convert + DVC
We couldn't use SRC sync convert mode together with DVC, but we can use workaround for it. This patch adds workaround and can use SRC sync convert + DVC Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Keita Kobayashi <keita.kobayashi.ym@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
