Shrink the stack sizes we need in coreboot

We accomplish this goal by getting rid of the huge auto array in the
    ram stage. This will in turn let us reduce CONFIG_STACK_SIZE.

We have to leave it on the stack in CAR as that's the simple way to
    keep it private. It does not matter then as there is only one core
    that is active.
