drivers: iio: adc: add support for ad4052

The AD4052/AD4058/AD4050/AD4056 are versatile, 16-bit/12-bit, successive approximation register (SAR) analog-to-digital converter (ADC) that enables low-power, high-density data acquisition solutions without sacrificing precision. This ADC offers a unique balance of performance and power efficiency, plus innovative features for seamlessly switching between high-resolution and low-power modes tailored to the immediate needs of the system. The AD4052/AD4058/AD4050/AD4056 are ideal for battery-powered, compact data acquisition and edge sensing applications. Signed-off-by: Jorge Marques <[email protected]>
