iio:adc:max9611: Switch to generic firmware properties.
Note the handling of the device tree node in this driver was somewhat
unusual. I have cleaned that up whilst also moving over to generic
properties.
Part of a general attempt to move all IIO drivers over to generic
firmware properties both as a general improvement and to avoid sources
of cut and paste into future drivers.
