BeagleBoard: Configure DVI/S-video

Browse Source 
Based on patches from Syed Mohammed Khasim (khasim@ti.com).

Configures the output of the BeagleBoard DVI to be orange.
Configures the output of the BeagleBoard S-Video to be a colorbar.

Changed display_init to beagle_display_init as suggested by Igor Grinberg:
