ASoC: Samsung: Add I2S S/W RST in startup function

Browse source 
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.
