[PATCH 1/5] sandbox: video: Display copy framebuffer if enabled

[Alper Nebi Yasak]

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.
