Renamed Adaptec 154x adapter source to Buslogic as now it emulates the Buslogic BT-540B SCSI adapter.
Moved CD-ROM read data buffer declaration and definitions to SCSI source files and headers, but still applying to IDE when needed. SCSI Read commands now return the correct sectors on callback. DMA bug fixes.
