This is a purely OF driver. There's no need for fwnode to handle any of
this, with the exception being phylik_create. Use of_fwnode_handle for
that.
Not sure this is worth cleaning up, but I'm not an OF API expert.
It's pretty odd that you're sneaking in an extra error check in
such a cleanup patch without even mentioning it.
git grep shows most drivers handling the error.

git grep of_get_phy_mode drivers/ | grep -v = | wc -l
7
git grep \ =\ of_get_phy_mode drivers/ | wc -l
48

I don't see why it should be different here.

Actually without handling the error, phy_mode gets used unassigned in
lan966x_probe_port

The fwnode API is different as it conflates int and phy_connection_t
as the same thing.

About the added error check - I agree with Jakub that this deserves to be
mentioned, and should be a patch on its own.
Sounds like a fix for net instead of net-next. Not sure how that would
work as both patches would conflict.
I did some testing on lan966x, and before the added error check, it was
actually possible to omit phy-mode from the DT, and still have a valid port
configuration - but then again, the bindings documents phy-mode as a required
property.. maybe this should be enforced in the code.
Absolutely.
As for the fwnode -> of changes, those looks good to me.
