[PATCH net 04/16] net: ethernet: aurora: nb8800: fix fixed-link phydev leaks

[Johan Hovold]

Make sure to deregister and free any fixed-link PHY registered using
of_phy_register_fixed_link() on probe errors and on driver unbind.

Fixes: c7dfe3abf40e ("net: ethernet: nb8800: support fixed-link DT
node")
