dt-bindings: net: qcom,ethqos: Correct fallback compatible for qcom,qcs615-ethqos

The qcs615-ride utilizes the same EMAC as the qcs404, rather than the
sm8150. The current incorrect fallback could result in packet loss.
The Ethernet on qcs615-ride is currently not utilized by anyone. Therefore,
there is no need to worry about any ABI impact.
