I haven't looked through the patch yet, since I'm waiting on more
information from Mika and Hartley's testing.

However, the commit log doesn't tell me why we want this change. Is it a
performance improvement? If so, do you have some numbers that we can
paste into the commit log?

In principle, using double buffering should be faster than using only
one buffer and disabling/enabling channel each time. But my measurements
doesn't show any significant change.

The real reason for this change is that current code is not 100% reliable
in IDE-DMA (I'm planning to submit ep93xx ide driver to linux-ide soon).

    IDE or libata driver? Asking because IDE drivers are not accepted anymore.
