This driver can handle SoC internal and external video bus multiplexers,
controlled either by register bit fields or by a GPIO. The subdevice
passes through frame interval and mbus configuration of the active input
to the output side.

- fixed a cut&paste error in vidsw_remove(): v4l2_async_register_subdev()
   should be unregister.

- added media_entity_cleanup() and v4l2_device_unregister_subdev()
   to vidsw_remove().

- added missing MODULE_DEVICE_TABLE().

- there was a line left over from a previous iteration that negated
   the new way of determining the pad count just before it which
   has been removed (num_pads = of_get_child_count(np)).

- Philipp Zabel has developed a set of patches that allow adding
   to the subdev async notifier waiting list using a chaining method
   from the async registered callbacks (v4l2_of_subdev_registered()
   and the prep patches for that). For now, I've removed the use of
   v4l2_of_subdev_registered() for the vidmux driver's registered
   callback. This doesn't affect the functionality of this driver,
   but allows for it to be merged now, before adding the chaining
   support.
