The sparx5_port_init() does initial configuration of a variety of
different features and options for each port. Some are shared for all
types of devices, some are not. As it is now, common configuration is
done after configuration of low-speed devices. This will not work when
adding RGMII support in a subsequent patch.

In preparation for lan969x RGMII support, move a block of code, that
configures 2g5 devices, down. This ensures that the configuration common
to all devices is done before configuration of 2g5, 5g, 10g and 25g
devices.
