V4L/DVB (3516): Make video_buf more generic
Video_buf were concerned to allow PCI devices to be used as video capture devices. This patch extends video_buf features by virtualizing pci-dependent functions and allowing other type of devices to use it. It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
