[PATCH RFC 0/2] Add Kconfig pages and cross-references to Documentation

[Nícolas F. R. A. Prado]

This series adds Kconfig pages (patch 1) to the Documentation, and
automarkups CONFIG_* text as cross-references to those pages (patch 2).

There is a huge change in build time with this series, so we'd either
have to so some optimization and/or put this behind a flag in make so it
is only generated when desired (for instance for the online
documentation):

  (On an XPS 13 9300)
  
  Before:
  
  real	6m43.576s
  user	23m32.611s
  sys	1m48.220s
  
  After:
  
  real	11m56.845s
  user	47m40.528s
  sys	2m27.382s

There are also some issues that were solved in ad-hoc ways (eg the
sphinx warnings due to repeated Kconfigs, by embedding the list of
repeated configs in the script). Hence the RFC.
