    [SCSI] hptiop: adding new firmware interface and more PCI device IDs
    
    updated patch based on Jeff Garzik's comments.
    
    - check adapter firmware version and use appropriate interface accordingly
    - add new PCI device IDs and use PCI_VDEVICE macro
    - update driver version string
    - remove unused data structures
    - remove unnecessary typecasts
