[PATCH 46/57] docs: cma/debugfs.txt: convert to ReST and move to admin-guide/mm

[Mauro Carvalho Chehab]

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.
