drm/mgag200: Remove HW cursor
The HW cursor of Matrox G200 cards only supports a 16-color palette
format. Univeral planes require at least ARGB or a similar component-
based format, so remove the HW cursor.
Alternatively, the driver could dither a cursor image from ARGB to
16 colors. But this does not produce pleasent-looking results in
general, so it's useless for modern compositors.
Without HW support, compositors will use software rendering.
