Input: rotary_encoder - add support for REL_* axes
The rotary encoder driver only supports returning input events
for ABS_* axes, this adds support for REL_* axes. The relative
axis input event is reported as -1 for each counter-clockwise
step and +1 for each clockwise step.
The ability to clamp the position of ABS_* axes between 0 and
a maximum of "steps" has also been added.
