doc: convert 'subsection' to 'section' in gfp.h

Patch series "Remove remaining parts of congestion tracking code", v2.

This patch (of 11):

Various DOC: sections in gfp.h have subsection headers (~~~) but the
place where they are included in mm-api.rst does not have section, only
chapters.

So convert to section headers (---) to avoid confusion.  Specifically if
sections are added later in mm-api.rst, an error results.
