xfree86/modes: Remove all framebuffer support from DGA

Browse source 
This removes all rendering and mapping code from xf86DiDGA, leaving
just mode setting and raw input device access. The mapping code didn't
have the offset within /dev/mem for the frame buffer and the pixmap
support assumed that the framebuffer was never reallocated.
(cherry picked from 0b7c6c728c)
