snd_pcm_ops is no longer needed. Let's use component driver callback.
*Note*
Only Intel skl-pcm has .get_time_info implementation, but ALSA SoC framework doesn't call it so far. To keep its implementation, this patch keeps .get_time_info, but it is still not called. Intel guy need to support it in the future.
