Move all jack-detect initialization to rt5651_set_jack_detect. The main reason to do this is so that platform code can setup jack-detect properties after the device has been probed, which unfortunately is necessary on some platforms.
This has 2 additional advantages: 1) Grouping all jack-detect init together makes it easier to follow what is happening and results in a small reduction in the number of loc. 2) Before we would register the irq handler before rt5651->hp_jack was assigned, leading to a potential NULL deref if the jack_detect work runs before the machine driver has called set_jack.
