ASoC: Change how suspend and resume obtain the PCM runtime
Currently only the atmel driver make use of snd_soc_dai.runtime field. If the dais are to be shared among two or more dai_links, the field must be got rid of. So, in atmel driver reach the substream via dai_link->pcm so as to not depend of snd_soc_dai.runtime field.
