[PATCH RFC 4/7] ASoC: samsung: i2s: Do not use platform_data for DMA parameters

[Sylwester Nawrocki <s.nawrocki@samsung.com>]

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.
