[PATCH 03/11] ASoC: Intel: avs: nau8825: Refactor jack handling

[Cezary Rojewski <cezary.rojewski@intel.com>]

From: Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com>

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.
