Fix build with CMOS support on various platforms

Browse Source 
When bringing in nvramtool as build_opt_tbl replacement,
various platforms where left in the cold that don't
provide direct IO support from userland (or at least not
in a way we support).

Build nvramtool without CMOS support when done as part of
a coreboot build. We don't need to touch CMOS in this case.
