Yes, the files are coming from the stock firmware image. The firmware image:
FRITZ.Box_4040.en-de-es-it-fr-pl.155.06.83.image can be found here [0].

In order to extract board data files:
 0. Download FRITZ.Box_4040.en-de-es-it-fr-pl.155.06.83.image
 1. tar xf FRITZ.Box_4040.en-de-es-it-fr-pl.155.06.83.image
 2. binwalk -e ./var/tmp/kernel.image

The boarddata_0.bin and boarddata_1.bin are located in:

eb866d036149fe4ba35f3f9d0d97e51969b1f1dbac6ea962daf9012ffa75427a  boarddata_0.bin
f3dc3c2f10037722006e9e7e5173a7468649e9a554f564323f9580f4a8bba10a  boarddata_1.bin

The boarddata_0.bin file matches the
file Sven attached (see checksums down below). And the boarddata_1.bin 
file matches the 
"bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=AVM-FRITZBox-4040" file
