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.
