When signalled by an external CEC device about to become a new active source, TIF(TvInputHardwareManager) sends an intent for TV app to tune to the input mapped to the device. For non-CEC devices or MHL device the device info comes with port ID only, which should be used to find the right input. Change-Id: I71c8454fead037d880ee440b0a8d64dd361ed558
