- Fix WaitOnBusy, WaitOnBaseBusy and Wait[Short]ForDrq to wait and loop exactly the same as our existing atapi driver. This greatly enhances uniata's compatibility, especially on modern highspeed hardware where a controller usually didn't have enough time to change its state and was considered invalid.
