[PATCH] libata: implement per-dev xfermask
Implement per-dev xfermask. libata used to determine xfermask
per-port - the fastest mode of the slowest device on the port. This
patch enables per-dev xfermask.
Original patch is from Alan Cox <alan@redhat.com>. The following
changes are made by me.
* simplex warning message is added
* remove disabled device handling code which is never invoked
(originally for choosing port-wide lowest PIO mode)
