[7/7] ASoC: samsung: Remove unused now unused struct s3c_dma_params

Commit Message

Sylwester Nawrocki/Kernel \(PLT\) /SRPOL/Staff Engineer/Samsung Electronics Aug. 4, 2016, 9:30 a.m. UTC

There is no user of this data structure now, all users have been converted
to use struct snd_dmaengine_dai_dma_data instead.
