The implicit fallback mechanism for searching the whole MDIO bus for at
least one PHY has been gone with the following commit b882005a18de
("drivers/net/fec: phy_init: remove redundant logic"). This lead to the
Ethernet driver erroring out as follows:
Net:   Could not get PHY for FEC0: addr -19
eth-1: fec@400d1000
Colibri VFxx # dhcp
Could not get PHY for FEC0: addr -19
Could not get PHY for FEC0: addr -19
Could not get PHY for FEC0: addr -19
Could not get PHY for FEC0: addr -19
No ethernet found.
Could not get PHY for FEC0: addr -19
Colibri VFxx #
This commit adds an explicit PHY node which makes it work again.
