V4L/DVB (3774): Create V4L1 config options

V4L1 API is depreciated and should be removed soon from kernel. This patch
adds two new options, one to disable V4L1 drivers, and another to disable
V4L1 compat module. This way, it would be easy to check what still depends
on V4L1 stuff, allowing also to test if app works fine with V4L2 only support.

           This kernel includes support for the new Video for Linux Two API,
           (V4L2) as well as the original system. Drivers and applications
           need to be rewritten to use V4L2, but drivers for popular cards
           and applications for most video capture functions already exist.
