MFC r242422:
Only four specific ATA PIO commands transfer several sectors per DRQ block
(interrupt).  All other ATA PIO commands transfer one sector or 512 bytes
at one time.  Hardcode these exceptions in ata(4) with ATA_CAM option.
This fixes timeout of READ LOG EXT command used by `smartctl -x /dev/adaX`.
