[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 Signed-off-by: HighPoint Linux Team <linux@highpoint-tech.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
