Commit 5a05a8200a ("davinci_emac:
use an unique MDIO bus name") introduced during the v3.3 merge
window updated the davinci mdio bus name to make it unique.
Update the bus name in board files which use DaVinci MDIO bus
to match the new name. Without this PHY is not detected with
error like:
PHY 0:01 not found
net eth0: could not connect to phy 0:01
Tested on DM365 and DA850 EVMs.
