[alsa-devel] DP audio API changes for identifying displays connected to a port

An additional parameter has been added to the API's between i915 and audio drivers to identify display devices that can be connected to the same port. Currently only the port identity is being shared, but this is not sufficient as multiple displays can be driven from the same port (E.g. DP MST). This patch makes the API changes with dummy changes in the audio driver (Thanks Libin). Implementation to fully enable DP MST audio will follow later.
