ASoC: rsnd: synchronize SSI start/stop sequence between PIO/DMA mode
Current SSI start/stop sequence is different between PIO/DMA mode, but, almost all are same. this patch synchronize it. It will be shared in the future. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
