ucc_geth: Revive fixed link support
Since commit 0b9da337dca972e7a4144e298ec3adb8f244d4a4 ("Rework ucc_geth driver to use of_mdio infrastructure") the fixed-link support is broken. This patch fixes the support by removing !ug_info->phy_node check, and adds a call to of_phy_connect_fixed_link() if a phy is not attached to the MAC. Also, remove an old fixed-link code that we don't use any longer.
