Via updates:
New PCI command parser. Moved from via_dma.c to via_verifier.c so functions
with similar functionality are close to eachother.
Moved video related functions to via_video.c, which might be extended in
the future, as new video functionality is added.
New device-specific generic IRQ IOCTL, similar to the general VBLANK IOCTL,
but with support for multiple device IRQ sources and functionality.
Support for Unichrome Pro PM800/CN400 video DMA commands in verifier and
PCI parser.
Support for Unichrome Pro PM800/CN400 HQV IRQs in the new generic IRQ
IOCTL.
Bumped minor. New version 2.6.0.
