The compat layer as well. So the only V4L1 code left is that for V4L1-only
drivers.
This means that V4L2 drivers can only be used by V4L2-aware applications
and can no longer be accessed by V4L1-only applications.

No V4L1-only drivers use videobuf, but videobuf has support for the V4L1
compat support in V4L2 drivers (the cgmbuf ioctl). So when we remove the
compat support, then that videobuf code can be removed as well.
