docs: add missing API types documentation

[Arno500]

The api-types.h file was not included during documentation generation, thus not being available in the online doc. It was containing some important structures used as arguments for some function calls.

Looks good, though could you update the commit message:

 WARNING: Possible unwrapped commit description (prefer a maximum 75 chars per line)
#6:

Error: WARNING: Possible unwrapped commit description (prefer a maximum 75 chars per line)

Thanks!

Fixed!

Ah checkpatch will still complain, because it expects a 'Signed-off-by: [email address]'

If you don't want to add your email just add your github handle that is also okay I suppose :)

Woops my bad, missed the second warning :/
Should be good now!

Thanks!
