The commit b31a1d8b41513b96e9c7ec2f68c5734cef0b26a4 changes the gianfar's phy id to the format like "mdio@xxxx:xx", but uec still uses the old format like "xxxxxxxx:xx". For the board whose UEC uses gianfar-mdio like MPC8568MDS, the phy can not be attached because of the incompatible phy id format. This patch changes uec's phy id to the same format as gianfar's.
