We handle the jack in/out event by rt5645_irq no matter who trigger the
irq. The jack detection event may generate by codec or an external
circuit. And rt5645_jack_detect will report the jack type.
If the jack detection event is generated by codec, we need to set
something to make it happen. This patch will configure the registers if
the platform is designed to use codec's JD function.
