[U-Boot] [PATCH v4 1/5] net: mdio-uclass: rename arguments of dm_mdio_phy_connect for clarity

[Alex Marginean]

Renamed dm_mdio_phy_connect arguments dev to mdiodev and addr to phyaddr
for a bit more clarity and consistency with the following patches.
Also use NULL instead of 0 on error return path.
