[PATCH input-acecad] config: remove AH_TOP autoheader statement

[Gaetan Nadon]

The generated config.h does not need to include xorg-server.h
for the content it provides.
Add #include <xorg-server.h> in .[hc] files as needed.

All drivers have this AH_TOP config line and I suspect only a few really need it.
Is there any reason (workaround or whatever) for xorg-server.h to be obtained
through this round about way?
