Subject: [PATCH 1/4] dt-bindings: arm: qcom,coresight-funnel: Add label for multi-ouput

Add new property "label" to label the source corresponding to the
output connection. When the funnel supports multi-output, this
property needs to be introduced to mark which source component a
certain output connection corresponds to.
