extcon: arizona: Declare 3-pole jack if we detect open circuit on mic
Detecting an open-circuit on the microphone pin, usually means the headset has a microphone but the cable is faulty. Currently the code will simply stop detecting and declare nothing in this situation. It is better to declare this as headphones such that the user can still use their headset as plain headphones even if the microphone is faulty.
