This reverts commit cdaf9af1eaeb539e32bfd6da6310b41ad6c3ba23
which breaks I2S support on non-DT platforms since default
"tx", "rx" DMA channel names for playback and capture streams
or custom channel names in struct snd_dmaengine_pcm_config
are supported in the ASoC dmaengine module only for DT case.
