iio: adc: ltc2309: use devm_regulator_get_enable_read_voltage()

Browse source

Use devm_regulator_get_enable_read_voltage() to simplify the code.
Error message is changed since there is only one error return now.
LTC2309_INTERNAL_REF_MV macro is added to make the internal reference
voltage value self-documenting.
