dt-bindings: iio: adc: ad4080: add AD4883 support

Browse Source 
Add AD4883 compatible string to the AD4080 devicetree binding.

The AD4883 is a dual-channel, 16-bit, 40 MSPS SAR ADC, sharing the same
register map and interface as the AD4080 family. Like the AD4880, it
requires two SPI chip selects and two io-backends for its independent
ADC channels. The AD4883 differs from the AD4880 in resolution (16-bit
vs 20-bit), which requires distinct channel configuration in the driver,
precluding a fallback compatible.
