ASoC: Intel: avs: da7219: Refactor jack handling

Use link->exit() rather than pdev->remove() to unassign jack during card
unbind procedure so codec link initialization and exit procedures are
symmetrical.

Also, there is no need to perform search for codec dai in suspend_pre()
and resume_post() ourselves. Use snd_soc_card_get_codec_dai() instead.
