ALSA: hda - Fix IDT/STAC multiple HP detection
Due to the recent change for multiple HP as line-out switch, only one of the multiple headphons (usually a wrong one) is toggled and the other pins are still disabled. This causes the silent output problem on some Dell laptops. Also, the hp_switch check is screwed up when a line-in or a mic-in jack exists. This is added as an additional output, but hp_switch check doesn't take it into account. This patch fixes these issues: simplify hp_switch check by using the NID instead of bool, and clean up / fix the toggle of HP pins in unsol event handler code.
