This is a generic setup for the headset input in CTIA mode.
Do you really need this explicity? Usually it's set up at
alc_headset_mode_ctia() when the iPhone type is connected.

The table is sorted in PCI SSID order. Please put at the right

Nowadays the less need for a new model name string. You can specify
the model with an alias of SSID if any other device needs to apply the
same quirk, too. So, unless it's mandatory, better to drop.
