Log Message:
viaide(4): Add support for VIA VT8261 IDE/SATA integrated controller.

The VT8261 southbridge, paired with the VN1000 chipset, is obscure and hard to
find. Besides some evaluation boards surfacing after Centaur's demise, at least
one rare production motherboard is known to exist.

Despite its rarity, the VT8261 is very similar to the VT8251. It uses separate
PCI IDs for PATA and SATA (IDE/RAID modes) with 4 SATA ports in total, 2 ports
sharing one channel, and maps registers through BAR5. This similarity made
adding basic support relatively simple (sharing same issues too).

Tested briefly on VIA VT8591B eval board.
