* Add multi device support.

For the moment up to 16 cards are supported.
  More can be added easily by changing 2 defines.
  This makes 90% of the patch (mostly stupid s/$var/card->$var/)
  The different devices can be accessed by different minor
  numbers (0-15):
  	mknod /dev/mga_vid0 c 178 0
  	mknod /dev/mga_vid1 c 178 1
  	mknod /dev/mga_vid2 c 178 2
  	mknod /dev/mga_vid3 c 178 3
	...
	ln -s mga_vid /dev/mga_vid

* Change the devfs code to let the kernel assign us
  a major and a minor number (what is the sense behind
  using devfs anyways if we dont do that ?)
  Subdevices for the different cards are created.
  mga_vid uses the first card (for compatibility)

* Fix a possible error when mmap() is called before
  the card is configured by a ioctl().
