[PATCH 2/2] iio: adc: ad7405: Add support for ADuM7801/7802/7811/7812

[Pop Ioan Daniel <pop.ioan-daniel@analog.com>]

Add a chip information structure and a device tree match table entry
for each of the ADuM7801, ADuM7802, ADuM7811 and ADuM7812. These parts
are handled the same way as the existing ADuM770x devices and differ
only in their full-scale input range: ±320 mV for the ADuM7801 and
ADuM7811, and ±64 mV for the ADuM7802 and ADuM7812.

Also list the new parts in the Kconfig help text.
