The patch_1/3 add an export of a function that calls the _detect_jack_

But why would anything ever call this function? How is this supposed to
be used?
In my opinion, this function is mainly to provide simple-card (patch_2/3).

This function will call and initialize jack detection if a codec supports it and fill the detect_jack function (patch_3/3 use it),
and, we don't need to create a customized machine driver to call the codec jack detection, the simple-card is able to
parse them.
