cpu/amd/car: Move AP stacks below the BSP stack to free up space
Caching SPD data during startup requires additional CAR space. There was a large chunk of free space between the AP stack top and the BSP stack bottom; moving the AP stacks below the BSP stack allows this space to be utilized. TEST: Booted ASUS KGPE-D16 with dual Opteron 6129 processors (16 cores) and 120k of CAR.
