[PATCH] libata: use correct map_db values for ICH8
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.
