V4L/DVB: cx2341x: convert to the control framework
Since this module is also used by drivers that are not yet converted, the old and new code have to co-exist. The source is split into three parts: a common part at the top, which is used by both old and new code, then the old code followed by the new control framework implementation. This new code is much more readable (and shorter!) than the original code. Once all bridge drivers that use this are converted the old code can be deleted.
