ASoC: soc-pcm: care trigger rollback

soc_pcm_trigger() calls DAI/Component/Link trigger,
but some of them might be failed.

	static int soc_pcm_trigger(...)
	{
		...
		switch (cmd) {
		case SNDRV_PCM_TRIGGER_START:
		case SNDRV_PCM_TRIGGER_RESUME:
		case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
			ret = snd_soc_link_trigger(substream, cmd);
			if (ret < 0)
				break;

(*)			ret = snd_soc_pcm_component_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_pcm_dai_trigger(substream, cmd);
			break;
		case SNDRV_PCM_TRIGGER_STOP:
		case SNDRV_PCM_TRIGGER_SUSPEND:
		case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
			ret = snd_soc_pcm_dai_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_pcm_component_trigger(substream, cmd);
			if (ret < 0)
				break;

			ret = snd_soc_link_trigger(substream, cmd);
			break;
		}
		...
	}

For example, if soc_pcm_trigger() failed at (*) point,
we need to rollback previous succeeded trigger.

This patch adds trigger mark for DAI/Component/Link,
and do STOP if START/RESUME/PAUSE_RELEASE were failed.

Because it need to use new rollback parameter,
we need to modify DAI/Component/Link trigger functions in the same time.
