AMD AGESA: Place CAR_GLOBAL in BSP stack
Use BSP CPU's stack space to store CAR GLOBALS for the
duration of romstage before CAR migration.
NOTE: Such globals can only be accessed from BSP CPU due
the way AMD platform has memory architecture set up.
TODO: Add compile-time assertions to verify CAR configuration
matches with the programming in vendorcode.
