Moved sample code found in Documentation/ to samples/ but kept actual
documentation where it is, while updating any in-text references to the
moved code. Updated the Documentation/Makefile and samples/Makefile to
reflect the change. Built with CONFIG_SAMPLES=y in .config with no
build errors. The directories added within samples/ still follow the
same structure that they did in Documentation. Directories in
Documentation/ that contained code still exist, only the code within
them has been moved out accordingly.
Documentation/Makefile: Removed subdirectories that no longer have any
code or Makefiles in them
samples/Makefile: Added references to the new subdirectories created
from the move
