mainboards/asus/kfsn4-dre: Run BSP FIDVID before AP FIDVID
This resolves an issue on Shanghai dual CPU configurations where the APs on node 0 would not start. Single CPU configurations are unaffected by this issue. TEST: Booted KFSN4-DRE with dual Opteron 8389 CPUs and verified proper BSP/AP start and microcode patch levels.
