chromeos: use cache-as-ram migration API for vbnv

It's possible that the vbnv global variables may be accessed
    in romstage after cache-as-ram is torn down. Therefore use
    the cache-as-ram migration API. Wrappers were written to
    wrap the API to keep the existing code as close as possible.
