iio: adc: Constify struct iio_map
'struct iio_map' are not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
In order to do it, the prototype of iio_map_array_register() and
devm_iio_map_array_register(), and a few structures that hold a
"struct iio_map *" need to be adjusted.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
21086 760 0 21846 5556 drivers/iio/adc/axp20x_adc.o
After:
=====
text data bss dec hex filename
21470 360 0 21830 5546 drivers/iio/adc/axp20x_adc.o
33842 1697 384 35923 8c53 drivers/iio/addac/ad74413r.o
