docs: cma/debugfs.txt: convert docs to ReST and rename to *.rst
The debugfs interface for CMA should be there together with other
mm-related documents.
Convert this small file to ReST and move it to its rightful place.
The conversion is actually quite simple: just add a title for the
document. In order to make it to look better for the audience,
also mark the "echo" command as a literal block.
While this is not part of any book, mark it as :orphan:,
in order to avoid build warnings.
