soc/intel/{adl, mtl}: Reduce CAR usage while using FSP debug binaries
Reduces the CAR (Cache-as-RAM) variable usage while using FSP debug binaries, which can prevent the CAR from becoming too full and unable
to integrate other CAR global variables.
This change has the following downsides:
- FSP debug output into the cbmem buffer will be partial.
To test this change, you can:
Build and boot google/rex without any function impact with non-serial
and serial FSP debug image (unless what has been documented here).
Bug=b:284124701
TEST=Able to build and boot google/rex.
