staging:iio: Remove legacy event handling.
This requires all drivers using the channel registration code and events to change in one go. V3: remove unwanted irq enable from event handler. V2: rebase related fixes to move to new IIO_CHAN macro. All trivial. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
