Use valid values for ICH8 map_db. With the old values, when the
controller was in Native mode, and SCC was 1 (drives configured for
IDE), any drive plugged into a slave port was not recognized. For
Combined Mode (and SCC is still 1), 2 is a value value for MAP.map_value,
and needs to be recognized.
