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.
