docs/mm: Physical Memory: remove useless markup 

Jon says:

  > +See also :ref:`Page Reclaim <page_reclaim>`.

  Can also just be "See also Documentation/mm/page_reclaim.rst".  The
  right things will happen in the HTML output, readers of the plain-text
  will know immediately where to go, and we don't have to add the label
  clutter.

Remove reference markup and unnecessary labes and use plain file names.
