Subject: [PATCH AUTOSEL 6.1 02/38] ASoC: SOF: sof-audio: start with the right widget type

From: Bard Liao <yung-chuan.liao@...ux.intel.com>

[ Upstream commit fcc4348adafe53928fda46d104c1798e5a4de4ff ]

If there is a connection between a playback stream and a capture stream,
all widgets that are connected to the playback stream and the capture
stream will be in the list.
So, we have to start with the exactly right widget type.
snd_soc_dapm_aif_out is for capture stream and a playback stream should
start with a snd_soc_dapm_aif_in widget.
Contrarily, snd_soc_dapm_dai_in is for playback stream, and a capture
stream should start with a snd_soc_dapm_dai_out widget.
