iio: adc: ti-ads1015: Replace data_rate with chip data struct ads1015_data
Instead of storing only data_rate in private data, store pointer to the
whole chip data and use the data_rate from chip data throughout the driver.
No functional change. This is done in preparation for switching to
read_avail().
