drivers: net: cpsw: don't ignore phy-mode if phy-handle is used

Browse Source 
The phy-mode emac property was only being processed in the phy_id
or fixed-link cases. However if phy-handle was specified instead,
an error message would complain about the lack of phy_id or
fixed-link, and then jump past the of_get_phy_mode(). This would
result in the PHY mode defaulting to MII, regardless of what the
devicetree specified.
