In the older code, headphone router is always on, it is not a good choose for low power demand.
This patch uses imx_hp_jack_gpio.jack_status_check to instead of w->event. It enables Ext Spk and disables Headphone Jack when Headphone Jack is plug in, it disables Headphone Jack and enables Ext Spk when Headphone is out.
