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

- fix all XXX showstoppers
|

- disable IR/IT DMA interrupts on shutdown
|
||||
- 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
