ASoC: soc-dai.h: cleanup Playback/Capture data for snd_soc_dai 

Current snd_soc_dai has data for Playback/Capture, but it is very
random. Someone is array (A), someone is playback/capture (B),
and someone is tx/rx (C);

	struct snd_soc_dai {
		...
(A)		unsigned int stream_active[SNDRV_PCM_STREAM_LAST + 1];

(B)		struct snd_soc_dapm_widget *playback_widget;
(B)		struct snd_soc_dapm_widget *capture_widget;

(B)		void *playback_dma_data;
(B)		void *capture_dma_data;

		...

(C)		unsigned int tx_mask;
(C)		unsigned int rx_mask;
	};

Because of it, the code was very complicated.
This patch creates new data structure to merge these into one,
and tidyup the code.
