ASoC: nuc900: patch for SUBSTREAM_TYPE', 'PCM_TX' and 'PCM_RX' removal
This patch is to remove the 'SUBSTREAM_TYPE','PCM_TX' and 'PCM_RX' definition. There is no need to redefine SNDRV_PCM_STREAM_PLAYBACK as PCM_TX, the SUBSTREAM_TYPE(substream) can be deleted too, the playback or record can be judged by 'if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK)' directly rather than 'if (PCM_TX == stype)', which makes the codes easy to read.
