Fix the bug that we got wrong phy_name on imx6q sabrelite board.
snprintf used wrong length of phy_name.
phy_name length is MII_BUS_ID_SIZE + 3 rather not MII_BUS_ID_SIZE.
I change it to sizeof(phy_name).

Since this patch fixes a regression seen on v3.3-rc1, it may be
suitable for -rc series.

The offending commit for the regression would be 391420f
(fec: use an unique MDIO bus name.) which increases the string
length of fep->mii_bus->id consequently mdio_bus_id.

Looks good to me since I introduced that "regression", but you already 
had a bug before my patch.
