890582c2a4 iio: adc: ltc2309: use devm_regulator_get_enable_read_voltage()
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.

733e0fed9c iio: adc: add ltc2309 support
The LTC2309 is an 8-Channel, 12-Bit SAR ADC with an I2C Interface.

This implements support for all single-ended and differential channels,
in unipolar mode only.
