iio: Add macro to populate struct iio_map array
The GPIO core provides a handy GPIO_LOOKUP() macro to populate a struct gpiod_lookup array without having to spell out attribute names (but still avoid breakage when attributes within the struct are rearranged or added). The axp288_adc.c driver uses a similar macro to populate a struct iio_map array. Make it available to others.
