realtek: dts: replace ports by ethernet-ports
In most drivers upstream use "ethernet-ports" instead of "ports"
in dts. Especially the upstream rtl9300 mdio driver uses this to
lookup the port/phy mapping. Do the same downstream. There is no
need to adapt the dsa driver because it scans the dts via
for_each_node_by_name(dn, "port").
