Input: automatically set EV_ABS bit in input_set_abs_params
Let's automatically set EV_ABS bit in device's event type list when calling input_set_abs_params() so that drivers do not have to do it explicitly. These calls are never in a hot paths so we won't lose much time by setting the same bit several times.
