iio: adc: ad4080: add support for AD4083
Add support for AD4083 16-bit SAR ADC. The AD4083 differs from
AD4080 in resolution (16-bit vs 20-bit) and LVDS CNV clock count
maximum (5 vs 7).
Changes:
- Add AD4083_CHIP_ID definition (0x0053)
- Create ad4083_channel with 16-bit resolution and storage
- Add ad4083_chip_info with lvds_cnv_clk_cnt_max = 5
- Register AD4083 in device ID and OF match tables
