Wayne Boyer d7b4627f5f [SCSI] ipr: adds PCI ID definitions for new adapters 
This patch adds the PCI ID definitions for new adapters based on the next
generation 64 bit IOA PCI interface chip.  New entries have been added to the
ipr_pci_table[] array for the adapters and to the ipr_chip[] array for the new
versions of the chip.

Older entries have been removed for cards that did not ship.
