Add AD4885 compatible string to the AD4080 devicetree binding. The AD4885 is a dual-channel, 16-bit, 10 MSPS SAR ADC, sharing the same register map and interface as the AD4080 family. Like the AD4884, it requires two SPI chip selects and two io-backends for its independent ADC channels. The AD4885 is the dual-channel variant of the AD4085 and differs from the AD4884 in its maximum throughput and LVDS conversion clock count, which requires distinct chip configuration in the driver, precluding a fallback compatible.

Add support for the AD4885, a dual-channel, 16-bit, 10 MSPS SAR ADC. The AD4885 is the dual-channel variant of the AD4085, sharing the same register map and SPI interface as the rest of the AD4080 family. Like the AD4884, it uses two independent ADC channels, each with its own SPI configuration interface, but it runs at a lower maximum throughput and therefore uses the same maximum LVDS conversion clock count as the AD4085.
