ASoC: jack: add snd_soc_codec_set_jack
There are many codecs with the capability of jack detection. Usually, we create a jack on machine driver but there is no common function for machine driver to deliver the jack pointer to codec driver. snd_soc_codec_set_jack can be used for delivering the jack pointer to codec driver and enable the jack detection function. To make it work, codec driver need to define a callback function to receive the jack pointer and do all necessary procedure for enabling jack detection.
