net: sparx5: skip low-speed configuration when port is RGMII

Browse Source 
When doing a port config, we configure low-speed port devices, among
other things. We have a check to ensure, that the device is indeed a
low-speed device, an not a high-speed device. Add an additional check,
to ensure that the device is not an RGMII device.
