Add a new API for getting audio_port_v7.
Add a function to audio HAL interface for retrieving audio_port_v7
structure directly. The legacy audio_port structure can always be
converted into audio_port_v7, however the latter may contain more
information.
This function must be supported from legacy HAL version 3.2.
