ASoC: Intel: avs: rt5682: Refactor jack handling

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

Leftover from recent series [1].
Following changes are proposed for the rt5682 sound card driver:

1) Move jack unassignment from platform_device->remove() to
   dai_link->exit(). This is done to make jack init and deinit flows
   symmetric
2) Remove platform_device->remove() function
3) Simplify card->suspend_pre() and card->resume_post() by making use of
   snd_soc_card_get_codec_dai() helper
