CBMEM: Fail builds on missing get_top_of_ram()
Dummy get_top_of_ram() is removed from romstage to fail already at build-time for cases where cbmem_initialize() would not complete. The mechanisms behind CAR_GLOBAL migration only work correctly when romstage can succesfully make the cbmem_initialize() call.
