So it looks like you need to add a phylink_fwnode_phy_connect(). And
maybe on top of that you need a phylink_device_phy_connect()?

So please stop. Take a step back, look at how the of_, device_,
fwnode_, and acpi_ abstractions all stack on top of each other, then
propose phylib and phylink core changes to implement these
abstractions.
