[5/8] ASoC: samsung: i2s: Do not use platform_data for DMA parameters

Commit Message

Sylwester Nawrocki/Kernel \(PLT\) /SRPOL/Staff Engineer/Samsung Electronics Nov. 10, 2016, 3:17 p.m. UTC

All related platforms use either devicetree or the DMA slave
map API for mapping DMA channels to slave devices so we can now
stop using platform_data for passing DMA details.
