[PATCH 3/4] dt-bindings: arm: qcom,coresight-tpdm: Mark tpda input port number

[Tao Zhang <quic_taozha@quicinc.com>]

Since the funnel supports multi-port output scenario, multiple
TPDMs may be connected to one TPDA. Add a new property
"qcom,tpda-input-port" to mark the input port number of the TPDA
in the device tree, TPDA driver can find out the right TPDM it needs
to search according to this new mark property.
