Add AP detection to stage0 to prevent APs from re-initializing mainboard setup that has already been done by the BSP. For single processor systems the CPU flag is always 0, BSP. This code also moves the AP stop for K8 mainboards to after memory setup so the AP's MTRRs can be setup to match system memory.
