iio: adc: rohm-bd79112: Use regmap_reg_range()

Initializing the regmap_ranges using direct assignment to the range_min
and range_max members is slightly verbose. We can make it a tad cleaner
when using the regmap_reg_range() macro.

Clean up the code using regmap_reg_range() when initializing the
regmap_range structure.
