ASoC: Drop SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag
Since commit 194c7dea00c68c1b1f8ff26304fa937a006f66dd "ASoC: dmaengine: add custom DMA config to snd_dmaengine_pcm_config" custom DMA channels can be also specified in chan_names[] field of struct snd_dmaengine_pcm_config. This patch removes chan_name field of struct snd_dmaengine_dai_dma_data as it is now unused.
