bsp-guide: Cleaned up some examples affected by VESA-support 

The Crown Bay BSP now only supports VESA graphics.  Because of
this, some of the examples in several areas of the BSP hierarchy
were wrong.  Changed accordingly.

All files that are needed for the BSP to support a display are kept here.
