description:
Add UDMA support for VIA VX900 media system processor IDE controller.
PR/46166 from Hiroshi Tokuda.

This should be pulled up to netbsd-6, since ZOTAC ZBOX nano VD01
http://www.zotacusa.com/zbox-nano-vd01.html
exhibited at NetBSD booth in Open Source Conference 2012 Tokyo Spring
was favored by many people.
