We force enable "Mic Det Power" when a jack is inserted. Also, we set codec idle_bias_off = true. As a result, codec driver will not suspend as we expect.
On Braswell, we don't need the jack detection when suspend but need it after resume, so export the jack suspend/resume APIs which are provided for machine driver to control during suspend/resume.
