Add device tree binding support for the AD4086 14-bit SAR ADC.
Add adi,ad4086 to the compatible enum.

A fallback compatible string to adi,ad4080 is not appropriate as the
AD4086 has different resolution (14-bit vs 20-bit) and LVDS CNV clock
count maximum (4 vs 7), requiring different driver configuration.
