Now that instances of input_dev support polling mode natively,
we no longer need to create input_polled_dev instance.

Applied to hwmon-next.

I don't know what 0-day is complaining about; the code builds
fine for me with the supposedly failing configuration. We'll
see if we get into trouble when the patch shows up in -next.
