ASoC: Samsung: Add I2S S/W RST in startup function
I2S module need to be reset after S2R. Keeping the S/W rst control part in resume didn't help in playing audio after resume. So this patch adds S/W RST control part in startup function which gets triggered for every new audio stream playback. Signed-off-by: Padmavathi Venna <padma.v@samsung.com> Signed-off-by: R.
