[PATCH 0/2] Fix build issues with Sphinx development tree

[Mauro Carvalho Chehab]

This Sphinx pull:
	https://github.com/sphinx-doc/sphinx/pull/8313

Fixes the C domain name conflicts when both a function and an
enum, struct or union have the same name. Those fixes will generate
new C domain warnings if an enum is defined using :c:struct.

So, we need to use different tags for structs or union. Thankfully,
such change is backward compatible with Shinx 3.x. The first
patch address it.

The second patch fix an issue at conf.py.

While Sphinx 4.0 was not released yet, the Sphinx development branch
is using 4.0.0 as its version. There is a small issue at the code that
excludes some macros from functions, if Sphinx major version is > 3.

  scripts: kernel-doc: use :c:union when needed
  sphinx: conf.py: properly handle Sphinx 4.0
