iio: adc: Convert to IIO_MAP()

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),
	...
	};

-		.adc_channel_label = LABEL,
