iio: adc: axp20x_adc: put ADC rate setting in a per-variant function
To prepare for a new comer that set a different register with different values, move rate setting in a function that is specific to each AXP variant. Signed-off-by: Quentin Schulz <quentin.schulz@free-electrons.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
