I know it's not a clean hack. In k3-am625-sk-u-boot.dtsi, as a hack,
the mdio pinctrl gets added to cpsw node. So was wondering if a duplicate
mdio pinctrl node could be added in the same file. Just wanted to know if we
could skip the changes in CPSW driver posted by Maxime. 

But Maxime's approach is much cleaner. We can just sync up kernel dts and not
keeping adding the hack to every K3 SoC's DT.
