[PATCH v6 3/5] dt-bindings: arm: Add qcom,qmi-id for remote etm

[Mao Jinlong]

Remote etm binding change was merged to fix the dt warning. Driver
changes were not merged at that time. qcom,qmi-instance-id is
required for remote etm driver to find the remote subsystem connection.
It is the instance id used by qmi to communicate with remote processor.
