ASoC: lpass-platform: don't use snd_soc_pcm_set_drvdata()

snd_soc_pcm_set_drvdata() will set driver data to rtd->dev,
but driver data of rtd->dev is already used as "rtd" on
soc_post_component_init().

	static int soc_post_component_init(xxx)
	{
		...
		dev_set_drvdata(rtd->dev, rtd);
		...
	}

To remove confusion, snd_soc_pcm_set/get_drvdata() should be
removed soon. This patch is for it.

qcom/lpass-platform.c sets struct lpass_pcm_data to rtd->dev today,
but we can replace it to struct lpass_data :: private_data.
