Unignore boards peripheral configuration in Doxygen

[LudwigKnuepfer]

Is there any particular reason to ignore all the periph_conf.h files?

With:

diff --git a/doc/doxygen/riot.doxyfile b/doc/doxygen/riot.doxyfile
index d2a396d..a657994 100644

I only got warnings in 4 files.

$ make doc >doclog 2>&1
$ grep warning doclog | grep periph | wc -l

Wouldn't it make more sense to document periph.conf at a central point instead of documenting each instance?

[LudwigKnuepfer]

No, because it specifies what is enabled per board.

[OlegHahm]

I see.

[haukepetersen]

agree with @LudwigOrtmann, I think the periph_conf files should be part of the doxygen documentation.

[PeterKietzmann]

So you agree to discard the periph_conf from the EXCLUDE_PATTERNS?

[haukepetersen]

yes
