[PATCH] remove broken video drivers 

Remove some video drivers that:

- had already been marked as BROKEN in 2.6.0 three years ago and
- are still marked as BROKEN.

These are the following drivers:
- FB_CYBER
- FB_VIRGE
- FB_RETINAZ3
- FB_SUN3

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive any of these drivers, the code is
still present in the older kernel releases.
