[PATCH 16/17] ASoC: Intel: bdw_rt286: Refactor suspend/resume

[Cezary Rojewski]

Make use of card->remove() rather than pdev->remove() to unassign jack
during card unbind procedure.

To reduce code size, define unified jack setter in form of
bdw_rt286_set_jack() and invoke it during remove(), suspend_pre() and
resume_port().
