ASoC: samsung: Drop usage of struct s3c_dma_params from spdif.c

struct s3c_dma_params already includes struct snd_dmaengine_dai_dma_data,
there is no need for such an indirection so switch to using struct
snd_dmaengine_dai_dma_data instead of struct s3c_dma_params.  This also
allows us to use snd_soc_dai_init_dma_data() function instead of the
platform specific samsung_asoc_init_dma_data helper.
