Add the video4linux driver for the "Multimedia eXtension Board",

an analogue tv card based on the saa7146.

Warning: Makefile and Kconfig will most likely be changed by
Gerd Knorr as well, so be sure to change these accordingly.

Warning2: "saa7111" is already available in the kernel, but needs
to be modified, as well as "video_decoder" in include/linux
