When VIDEO_COPY is enabled, the "main" framebuffer is a cached work area in U-Boot allocated memory and the "copy" framebuffer is the hardware frame buffer displayed on the screen. The sandbox SDL video driver sets copy_base to indicate support for this, but it displays the work area instead. Change it to display the copy buffer if enabled.
