ASoC: Intel: avs: Refactor jack handling

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

For all the boards included in this patchset, a similar set of changes
is proposed:

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

While bdw_rt286 board - which is utilized by the catpt-driver - is
definitely not part of "avs", same treatment applies. And thus decided
to make it part of this series instead of sending it separately.
