Noticed whilst adding MODULE_IMPORT_NS() as I missed some files and
it still worked, making it clear not all of these blocks were needed.

The atmel,trigger-edge-type was never imposed by the driver.
Make things right and remove this property from the mandatory list.
This will not break existing nodes because according to the binding they
should have this property.
However, the driver does not impose it and it works without it, the property
selects the trigger type, and without it, the driver will have no trigger
available, which is the case on some boards which do not have access
to the trigger pin.
This will avoid generating this warning for example:

When a consumer calls iio_read_channel_processed() and no channel scale
is available, it's assumed that the scale is one and the raw value is
returned as expected.
On the other hand, if the consumer calls iio_convert_raw_to_processed()
the scaling factor requested by the consumer is not applied.
This for example causes the consumer to process mV when expecting uV.
Make sure to always apply the scaling factor requested by the consumer.
