[SCSI] aacraid driver update

changes:

- set aac_cache=2 as default value to avoid performance problem
(Novell bugzilla #469922)

- Dell/PERC controller boot problem fixed (RedHat bugzilla #457552)

- WWN flag added to fix SLES10 SP1/SP2 drive detection problems

- 64-bit support changes

- DECLARE_PCI_DEVICE_TABLE macro added

- controller type changes
