Input: gpio_keys_polled - add support for abs/rel axis
This changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver. The driver already allows specifying what type of events (key / rel / abs) a button generates when pressed, but for rel / abs axis we also need to specify which value this specific gpio represents. One use case is digital joysticks / direction-pads which are hooked up to gpio, in this case we've left and right buttons which we want to map to EV_ABS, ABS_X and we want generate events for left with a value of -1 and for right with a value of +1 (and similar for up / down and ABS_Y).
