[SCSI] hptiop: Add RR44xx adapter support
Most code changes were made to support RR44xx adapters. - add more PCI device ID. - using PCI BAR[2] to access RR44xx IOP. - using PCI BAR[0] to check and clear RR44xx IRQ. Signed-off-by: HighPoint Linux Team <linux@highpoint-tech.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
