ASoC: audio-graph-card2: add comment for format property 

We don't need to have "format" property on DT any more if
CPU/Codec driver has .auto_selectable_formats settings
on snd_soc_dai_ops. The sample dtsi doesn't have it.
To avoid user confusion, this patch indicates it on comment.

"format" property is no longer needed on DT if both CPU/Codec drivers are
supporting snd_soc_dai_ops :: .auto_selectable_formats.
