scsi: pm80xx: Increase the number of outstanding I/O supported to 1024
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.
[mkp: fixed zeroday complaint]
