The pm80xx driver currently sets the controller queue depth to 256. Hoewver, the controller supports outstanding I/Os up 1024. Increase the number of outstanding I/Os from 256 to 1024. CCBs and tags are allocated according to outstanding I/Os. Also update the can_queue value (max_out_io - PM8001_RESERVE_SLOT) used by the SCSI midlayer.
