This patch adds an option to skip the video initialization on for all
video drivers. This is needed for the CPCI750 which can be built as CPCI
host and adapter/target board. And the adapter board can't access the
video cards located on the CompactPCI bus.

This patch replaces the previous one [video: ct6900: Add an option to skip
video initialization]. The test is now moved out of the ct6900 file into
the generic video init routine drv_video_init() as suggested by Anatolij.
Thanks,
Stefan
