video: mcde: Add fake color map functionality
Implements a non functional cmap functionality in order
to make X11/fbdev happy. Lack of functionality will make
no difference on modern panels due to the fact that most
panels use 16 or more bits for color depth anyway.
Corresponds to bug 803814 on Linaro-ubuntu
