ASoC: soc-pcm: remove dpcm_do_trigger()

dpcm_be_dai_trigger() is calling dpcm_do_trigger()
at each SNDRV_PCM_TRIGGER_xxx (1).

	int dpcm_be_dai_trigger(...)
	{
		for_each_dpcm_be(fe, stream, dpcm) {
(B)			...
			switch (cmd) {
			case SNDRV_PCM_TRIGGER_START:
				...
(1)				ret = dpcm_do_trigger(...);
				...
			case SNDRV_PCM_TRIGGER_RESUME:
				...
(1)				ret = dpcm_do_trigger(...);
				...
			case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
				...
(1)				ret = dpcm_do_trigger(...);
				...
			case SNDRV_PCM_TRIGGER_STOP:
				...
(1)				ret = dpcm_do_trigger(...);
				...
			case SNDRV_PCM_TRIGGER_SUSPEND:
				...
(1)				ret = dpcm_do_trigger(...);
				...
			case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
				...
(1)				ret = dpcm_do_trigger(...);
				...
			}
		}
	}

But it is just very verbose and duplicated function.
Because We can indicate dev_dbg() (A) at dpcm_be_dai_trigger() (B).
And dev_err() (C) is not needed because soc_pcm_trigger() itself
indicates error message when error.

	static int dpcm_do_trigger(...)
	{
		int ret;

(A)		dev_dbg(...);

		ret = soc_pcm_trigger(substream, cmd);
		if (ret < 0)
(C)			dev_err(...);

		return ret;
	}

This patch replace dpcm_do_trigger() to soc_pcm_trigger().
