[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
