Subject: [PATCH] [media] vivid: add CONFIG_FB dependency

The vivid test driver creates a framebuffer, which fails if the the framebuffer layer is not enabled:

drivers/built-in.o: In function `vivid_fb_release_buffers':
:(.text+0x2acfe8): undefined reference to fb_dealloc_cmap' drivers/built-in.o: In function vivid_fb_init':
:(.text+0x2ad344): undefined reference to fb_alloc_cmap' :(.text+0x2ad34c): undefined reference to register_framebuffer' drivers/built-in.o: In function `vivid_exit':
:(.exit.text+0x4354): undefined reference to unregister_framebuffer' drivers/built-in.o:(.data+0x55f88): undefined reference to cfb_fillrect' drivers/built-in.o:(.data+0x55f8c): undefined reference to cfb_copyarea' drivers/built-in.o:(.data+0x55f90): undefined reference to cfb_imageblit'

This adds the dependency in Kconfig.
