nb/amd/mct_ddr3: Use correct initial UI setting during DRAM training
Rebasing change I3be808db5d15ceec4c36d17582756b01425df09a
did not take into account the default UI setting introduced in
change I6ae88c891e92b21dc0ca3c47b8f3d269f83b3204 , causing DRAM
instability and occassional failure to boot.
Use the correct 1UI value for the modified function semantics.
