ASoC: Add jack reporting interface

This patch adds a jack reporting interface to ASoC.  This wraps the ALSA
core jack detection functionality and provides integration with DAPM to
automatically update the power state of pins based on the jack state.

Since embedded platforms can have multiple detecton methods used for a
single jack (eg, separate microphone and headphone detection) the report
function allows specification of which bits are being updated on a given
report.

The expected usage is that machine drivers will create jack objects and
then configure jack detection methods to update that jack.
