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.
