Currently DAI playback and capture widgets are created during soc_probe_codec and soc_probe_platform using the device associated with the platform/codec to locate the DAI upon which the widgets should be created. If a device registers both a CODEC and platform driver this leads the widgets created during CODEC probe being overwritten by the widgets created during the platform probe.
In general we want to retain the existing playback and capture widgets because routes may have already been added to them. This patch will check for existing widgets during snd_soc_dapm_new_dai_widgets and only create new widgets if none exist.
