Log Message:
viaide(4): identify and attach VT6420 IDE (PATA) controller.

The VT6420 is an independent version of the integrated VT8237R SATA RAID and
IDE controller, sharing the same PCI ID as the southbridge SATA controller.
The PATA controller, on the other hand, has a unique PCI ID, since the
integrated one reuses the same PCI ID as many other VIA southbridges and ISA
bridge identification would not work with this controller. The controller is
quite rare (likely due to the SATA autonegotiation bug), so it seems nobody
added this PCI ID to any major OS.

Tested on Biostar M7NCD Ultra.
