Explicitly clear 1000baseT control register for F1 PHY used in AR8132 FastEthernet controller. The PHY has no ability to establish a gigabit link. Previously only link parters which support down-shifting was able to establish link. This change should fix a long standing link establishment issue of AR8132.
