ASoC: dmaengine-pcm: Remove snd_dmaengine_pcm_{set,get}_data 

These functions were initially added to be able to support some oddball dma
drivers, but all users have been updated to deal with the situation without the
help of snd_dmaengine_pcm_{set,get}_data, so these two functions can be removed.
