iio: adc: add max11410 adc driver

Adding support for max11410 24-bit, 1.9ksps delta-sigma adc which has 3 differential reference and 10 differential channel inputs. Inputs and references can be buffered internally. Inputs can also be amplified with internal PGA. Device has four digital filter modes: FIR50/60, FIR50, FIR60 and SINC4. FIR 50Hz and 60Hz rejections can be enabled/disabled separately. Digital filter selection affects sampling frequency range so driver has to consider the configured filter when configuring sampling frequency.
