unsolicited event was not enabled at node 0x0f

but the pin fix from line out (misc=no_presence) to a hp with detection

and this change enabled the unsolicited event and create the headphone jack detection.control

it seem that utomute is peformed by hardware which cannot provide jack state to user space
