[PATCH 1/2] dt-bindings: iio: adc: ad4080: add AD4884 support

[Antoniu Miclaus <antoniu.miclaus@analog.com>]

Add AD4884 compatible string to the AD4080 devicetree binding.

The AD4884 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.
