It can merge 2 LM/DSPP outputs and feed it to a single interface. Enable 3D Mux if our mdp5_pipeline has 2 active LMs. This check will need to be made more specific later when we add Dual DSI support with source split enabled. In that use case, each LM feeds to a separae INTF, so the 3D mux isn't needed.
