Add support for the Promise PDC20771, present on the Promise FastTrak TX2300. 

This support is not based on a datasheet, because a datasheet is not readily
available for this chip.  However, Promise have partially open sourced their
driver for Linux, and all suggestions are that the PDC20771 is pretty similar
to other recent SATA chips.

The TX2300 has two ports, but there is unoccupied space on the board for a
third PATA port.  It isn't entirely obvious how many channels the PDC20771 can
support.

The pdc205xx_drv_probe probe is necessary to avoid probing two wd* devices for
every physical device.
