[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
