AGESA boards: Fix regressions with LATE_CBMEM_INIT

Some configurations of AGESA boards fail to boot after commit
  61be360 AGESA: Fix UMA calculations

Implementation of cbmem_find() for ENV_ROMSTAGE expects
that CBMEM has already been initialized. In the case of
LATE_CBMEM_INIT boards, this is not the case and cbmem_top()
returned NULL prior to the offending commmit.

By definition LATE_CBMEM_INIT does not have known cbmem_top()
in ENV_ROMSTAGE except for possible ACPI S3 resume path.
