iio: adc: Convert to IIO_MAP()

Use IIO_MAP() instead of hand-writing it. It is much less verbose.

The change has been do with the following coccinelle script:

@@
identifier STRUCT_NAME;
constant NAME, CHANNEL, LABEL;
@@

static const struct iio_map STRUCT_NAME[] = {
...,
- {
- .consumer_dev_name = NAME,
- .consumer_channel = CHANNEL,
- .adc_channel_label = LABEL,
- },
+ IIO_MAP(LABEL, NAME, CHANNEL),
...
};

...,
- {
- .consumer_dev_name = NAME,
- .adc_channel_label = LABEL,
- },
+ IIO_MAP(LABEL, NAME, NULL),
...
};
