ASoC: audio-graph-card2: recommend to use auto select DAI format

Browse Source 
"Simple Audio Card", "Audio Graph Card", "Audio Graph Card2" are
possible to set DAI format via DT.

OTOH, ASoC is supporting .auto_selectable_formats to select DAI
format automatically. Let's recommend to use it on "Audio Graph Card2".
One note is that it keeps supporting DAI format setting via DT.
