drm/mgag200: Add FB_DAMAGE_CLIPS support
The driver does support damage clips, but doesn't advertise it. So when running gnome/wayland on Matrox hardware, the full frame is copied to the slow Matrox memory, which leads to very poor performances. Add drm_plane_enable_fb_damage_clips() to advertise this capability to userspace. With this patch, gnome/wayland becomes usable on Matrox GPU.
