dmx: provide enough space for axis mappings

relmap/absmap is used as a evdev-axis-to-x-axis mapping. ABS_X maps to
axis 0, ABS_Y to 1, etc. skipping over non-existing axes so that the third bit
set in the ABS_* range is axis 2, and so on. This requires us to actually have
enough space to have all the ABS_*/REL_* range.
