[PATCH v2 0/3] doc: global data pointer

Add the description of the global data pointer to the generated HTML documentation.

The first patch converts the GD_FLG_* constants to an enum. The second adds move Sphinx comments. The third finally provides the HTML documentation.

v2: enum gd_flags must not be exposed to assembler code. This avoids a build failure on x86.
