[U-Boot] [PATCH v1] colibri_vf: fix ethernet by adding explicit phy node

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

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 at 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.
