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

- 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
