Subject: [PATCH] Fix issue: 2413494: [Passion-c] Add TTY support.

AudioHardware receives TTY mode selection from HeadsetObserver by means of the setParameters() method.
Whenever the audio mode is MODE_IN_CALL and a headset is connected, the sound device selection
is modified by TTY mode in order to select TTY full, VCO ot HCO oudio routes and a1026 configuations accordingly.
