[PATCH 3/3] ASoC: soc.h: use array instead of playback/capture_widget

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

snd_soc_pcm_runtime has playback/capture_widget for Codec2Coddec.
The naming is unclear.
This patch names it as c2c_widget and uses array.

	struct snd_soc_pcm_runtime {
		...
=>		struct snd_soc_dapm_widget *playback_widget;
=>		struct snd_soc_dapm_widget *capture_widget;
		...
	}
