Subject: [PATCH 3/4] 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,
today the of_phy_connect() will try to find a fixed PHY if the
phy_node appears to be NULL.

Also, remove an old fixed-link code that we don't use any longer.
