1. Add new FE capabilities to support:

a. Parallel playback on 2 ports simultaneously Define new frontends to enable additional playback port. This will be used when platform needs to support multi-playback on different ports. Ex: Headset and Speaker simultaneously b. Echo reference capture capability Certain platforms need reference stream of playback to supplement User-space post-processing algorithms. This pin enables platform driver to provide such a FE. 2. Add DAI links for parallel playback and echo ref 3. Add map for new DAIs for parallel playback and echo ref
