The inet9f-rev03 tablet has multiple fire-buttons / direction controls,
add support for these using the same axis mapping as ps2 compatible game
controllers with the same stick / button layout use.

Changes in v2:
-Do not include dt-bindings/input/evdev.h, as the necessary evdev codes
have been added to dt-bindings/input/input.h instead
