*-internal-delay-ps properties would be applicable only for RGMII interface modes. It is changed as per the request, https://lore.kernel.org/netdev/d8e5f6a8-a7e1-dabd-f4b4-ea8ea21d0a1d@gmail.com/ (local) Ran dt_binding_check to confirm nothing is broken and submitting as a RFC patch to receive feedback.
