From: Michael Gruber <lists.mg@xxxxxxxxxxxxxx>
If the new module option force_dpad_to_buttons is set, the directional pad will
be mapped to 4buttons instead of 2axes for all controllers. This includes those
in the list of known controllers which are not affected by the existing option
dpad_to_buttons.

The ability to switch between axes and buttons mode is already present in the
driver but it is only possible if the connected controller is not known by the
driver. This patch makes the feature available for all pads.
