[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.

- * A small info on how to convert XFree86 timing values into fb

- *
-An XFree86 mode line consists of the following fields:
- "800x600"     50      800  856  976 1040    600  637  643  666
- < name >     DCF       HR  SH1  SH2  HFL     VR  SV1  SV2  VFL
-
-The fields in the fb_var_screeninfo structure are:
-        unsigned long pixclock;         * pixel clock in ps (pico seconds) *
-        unsigned long left_margin;      * time from sync to picture    *
-        unsigned long right_margin;     * time from picture to sync    *
-        unsigned long upper_margin;     * time from sync to picture    *
-        unsigned long lower_margin;
-        unsigned long hsync_len;        * length of horizontal sync    *
-        unsigned long vsync_len;        * length of vertical sync      *
-
-1) Pixelclock:
-   xfree: in MHz
-   fb: In Picoseconds (ps)
-
-   pixclock = 1000000 / DCF
-
-2) horizontal timings:
-   left_margin = HFL - SH2
-   right_margin = SH1 - HR
-   hsync_len = SH2 - SH1
-
-3) vertical timings:
-   upper_margin = VFL - SV2
-   lower_margin = SV1 - VR
-   vsync_len = SV2 - SV1
-
-Good examples for VESA timings can be found in the XFree86 source tree,
