The directory structure has been in place from the initial merge of the 
subsystem, before Alex and myself took on the maintainer roles.

I see no reason for a move though. The extra burden for backports, etc 
outweigh the urge of cleanliness on the folder structure. :-)

The Kconfig cleanup and move of the file is worth doing, the move of the 
whole source code folder not.
