Subject: [PATCH 4/9] ASoC: qdsp6: audioreach: Simplify handing FE and BE graph connections
Current AudioReach design of connecting FE and BE graph is very complicated
and not reliable. Instead used the virtual damp widgets private data to help
identify the modules that needs connection at runtime. Also maintain a
inter-graph connection info in the graph info, which can be used to both
determine if the graphs are connected and at graph build time.
