ieee1394: remove devfs support
Devfs has been disabled in the last kernel releases, so let's remove it from ieee1394core, raw1394, video1394, dv1394.

- flush pci writes to the card by issuing a read

- devfs and character device dispatching (* needs testing with Linux 2.2.x)

- character device dispatching
|

- switch over to the new kernel DMA API (pci_map_*()) (* needs testing on platforms with IOMMU!)

- keep all video_cards in a list (for open() via chardev), set file->private_data = video
|
||||
- dv1394_poll should indicate POLLIN when receiving buffers are available
