video/cmdline: Introduce CONFIG_VIDEO for video= parameter

Browse Source 
Add CONFIG_VIDEO for common code in drivers/video/. Use the option to
select helpers for the video= parameter. Replaces CONFIG_VIDEO_CMDLINE.

Other common code in drivers/video/ can be moved behind CONFIG_VIDEO,
which will simplify the Kconfig rules.
