That included the object tree as well as the configuration tables. Now however we don't recreate them, which means we must not explicitly override the configuration tables, as otherwise we may lose our SMBIOS table from the configuration table list on second bootefi invocation. This patch makes bootefi call our normal configuration table modification APIs to add/remove the FDT instead of recreating all tables from scratch. That way the SMBIOS table gets preserved across multiple invocations.
