Subject: [PATCH v3 2/2] ASoC: dt-bindings: audio-graph-port: Document new DAI link flags playback-only/capture-only

From: Daniel Baluta <daniel.baluta@....com>

Document new playback-only and capture-only flags which can be used
when dai link can only support just one direction: playback or capture
but not both.
