Add a new property "filter_src" to label the source corresponding to the output connection for a static replicator. By combining a funnel and a static replicator in devicetree, a new device that supports multi-port input and multi-port output is implemented. In order to match the output port with the input port and successfully build the trace path, add this new property to indicate the data source corresponding to this output port.
