Now that the staged configuration holds its CDP type and hardware
closid, allow resctrl to stage more than configuration at a time for
a single resource.
To detect the same schema being specified twice when the schemata file
is written, the same slot in the staged_configuration array must be
used for each schema. Use the cdp_type enum directly as an index.
