[PATCH] Revert "drm: Update fbdev fb_fix_screeninfo"

[Dave Airlie]

From: Dave Airlie <airlied@xxxxxxxxxx>

This reverts commit dfe63bb0ad9810db13aab0058caba97866e0a681.

This commit was causing nouveau not to work properly, for -rc1 I'd prefer it
worked and we can look if this is useful for 2.6.39.
