Implement per-dev xfermask.  libata used to determine xfermask

patch enables per-dev xfermask.

Original patch is from Alan Cox <alan@xxxxxxxxxx>.  The following
changes are made by me.

* simplex warning message is added
* fix port-wide PIO mode selection to aovid violating device selection
  timing.

Since Alan squawked, perhaps break the port-wide PIO mode selection into a separate patch, so that the other stuff can go in?

Then longer term we can figure out what it the best course of action.
