subdev_pad_ops and video_ops both contains operation related
to format, crop and bus format.
When should one or the other be used ?
For example mt9p031 implement everything using pad_ops, but other drivers
use video_ops functions.

The pad ops are required by the media controller framework. New drivers should
use pad ops for format and selection handling. We need wrappers to translate
video ops to pad ops to be used by bridge drivers that don't support pad ops
yet.
