Added the NCR 53c815 and 53c820, and made sure the 53c810 and the 53c820 do not have the BIOS option as real ones do not have a BIOS BAR, while the 53c815 and 53c825 do (they are basically 53c810 and 53c820, respectively, with own BIOS support);

Roughly implemented the SCSI IDENTIFY message LUN operation, fixes some SCSI controller drivers in some situations;
Added an undocumented CMD640 IDE controller register required by Linux and by a DOS driver.
