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.
