This changes the argument for the interrupt handler to be the IIO device instead of the state-struct. Since there will be some changes to how iio_priv_to_dev() is implemented, it could be that the helper becomes a bit slower, as it will be hidden away in the IIO core.
The iio_priv() call will still be fast enough, as it will return a void pointer from the public IIO device structure. So it's better to switch the order.
