[media] v4l: Add custom compat_ioctl32 operation
Drivers implementing custom ioctls need to handle 32-bit/64-bit compatibility themselves. Provide them with a way to do so. To avoid circular module dependencies, merge the v4l2-compat-ioctl32 module into videodev. There is no point in keeping them separate, as the v4l2_compat_ioctl32() function is required by videodev if CONFIG_COMPAT is set anyway.
