This commit adds bindings support for AD4113. The AD4113 is a low power, low noise, 16-bit, Σ-Δ analog-to-digital converter (ADC) that integrates an analog front end (AFE) for four fully differential or eight single-ended inputs. Added ad4113 to the compatible list and the "avdd2-supply: false" restriction.
