If we want to do this, we should better handle the input device portion
of the driver. We have 2 options:

- switch the input device into polling mode when interrupt is absent
- do not create input device

Those do not need to be mutually exclusive (i.e. we could use absence of
both device tree interrupt property as well as lack of poll-interval
property to suppress creation of the input device and only leave iio.

Thanks.
