- Remove several hacks that didn't do much but waste cycles.
...
- Disable interrupt-driven PDMA when writing (use polled PDMA instead).
- Be more careful about when to flag a transfer as completed.
The result of these changes is that interrupt-driven PDMA works well
enough to bring the system up.

...
fixes the following problems:
- Timeout on START/STOP unit command (ie. when spinning up the drive)
Side effect of this fix is to reduce the busy-wait time in CMD phase.
- Occasionally, the driver would lose an SBIC interrupt, especially when
a tape drive was re-selecting on a busy SCSI bus.

- Changed ledma attach code to pay attention to the PROM's notion of what
cable type is being used. Note that this patch does not fix the problem
recently discussed on port-sparc; in most cases the PROM doesn't know
what cable type is being used. The default is now TP rather than AUI,
though. A complete fix is forthcoming.
