This is particularly relevant for device that have 2.5G or 10G port connected to port5 or port 6 on ipq8074. As the parent are shared across multiple port it may be required to select the correct configuration to accomplish the desired clock. Without this patch such port doesn't work in some specific ethernet speed as the clock will be set to the wrong frequency as we just select the first configuration for the related frequency instead of selecting the best one.
