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

Commit Message

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.

If we remove the filter argument from every caller here, maybe we should also
change the prototype to not expect those three NULL arguments any more.

There is one occurrence where the third argument needs to be not NULL.
I'm planning to modify sound/sound/samsung/i2s.c so there is no need
to create another platform device just for the overlay DAI, afterwards
the above function could be simplified.
