Add an appropriate entry for the Promise PDC42819 controller. It has an
AHCI mode and seems to work correctly with board_ahci.
This chip is found on Promise's FastTrak TX2650 (2 port) and TX4650 (4 port)
software-based RAID cards (for which there is a binary driver, t3sas) and
can be found on some motherboards, for example the MSI K9A2 Platinum,
which calls the chip a Promise T3 controller.

Apparently this chip also supports SAS disks, will these work with the
ahci driver (I've only tested with normal desktop SATA disks)?
