Export drm_fb_helper_damage() and drm_fb_helper_damage_range(), which handle damage areas for fbdev emulation. This is a temporary export that allows to move the DRM I/O helpers for fbdev into drivers. Only fbdev-generic and i915 need them. Both will be updated to implement damage handling by themselves and the exported functions will be removed.
