[media] v4l2-subdev: Allow 32-bit compat ioctls ...
Add support for 32-bit ioctls with v4l-subdev device nodes.
Rather than keep adding new ioctls to the list in v4l2-compat-ioctl32.c, just check
if the ioctl is a non-private V4L2 ioctl and if so, call the conversion code.
We keep forgetting to add new ioctls, so this is a more robust solution.
In addition extend the subdev API with support for a compat32 function to
convert custom v4l-subdev ioctls.
