iio: adc: Add ad7124 support The ad7124-4 and ad7124-8 are a family of 4 and 8 channel sigma-delta ADCs with 24-bit precision and reference. Three power modes are available which in turn affect the output data rate: * Full power: 9.38 SPS to 19,200 SPS * Mid power: 2.34 SPS to 4800 SPS * Low power: 1.17 SPS to 2400 SPS The ad7124-4 can be configured to have four differential inputs, while ad7124-8 can have 8. Moreover, ad7124 also supports per channel configuration. Each configuration consists of gain, reference source, output data rate and bipolar/unipolar configuration.
