This has to be protected with ifdef CONFIG_DM_ETH as dev->of_offset is
available only in DM_ETH
Build error for non-dm-eth case
drivers/net/cpsw.c: In function ‘cpsw_phy_init’:
drivers/net/cpsw.c:970:14: error: ‘struct eth_device’ has no member
named ‘of_offset’
phydev->dev->of_offset = slave->data->phy_of_handle;
