V4L/DVB (5902): Add ivtv-fb framebuffer driver.
Add the ivtv-fb framebuffer driver for cx23415 devices (currently
only the Hauppauge PVR-350 cards). This makes it possible to use
the On-Screen Display functionality of these cards, either for menus
during MPEG playback, or as a console or X display.
