[SCSI] aacraid: Added Sync.mode to support series 7/8/9 controllers
Added Sync. mode to support Series 7/8/9 controller families: This is a compatibility mode for all these controller families. The Async. (Performance) mode can be changed in the future. First Async. mode version added for Series 7; Controller parameter aac_sync_mode added Signed-off-by: Mahesh Rajashekhara <aacraid@pmc-sierra.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
