V4L/DVB (5902): Add ivtv-fb framebuffer driver.

Browse Source 
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.

This is a framebuffer driver for the Conexant cx23415 MPEG
encoder/decoder.
This is used in the Hauppauge PVR-350 card. There is a driver
homepage at <http://www.ivtvdriver.org>.
