dt-bindings: iio: adc: adi,ad4080: add support for AD4087

Add device tree binding support for the AD4087 14-bit SAR ADC.
Add adi,ad4087 to the compatible enum.

A fallback compatible string to adi,ad4080 is not appropriate as the
AD4087 has different resolution (14-bit vs 20-bit) and LVDS CNV clock
count maximum (1 vs 7), requiring different driver configuration.
