[PATCH v4 3/7] iio: adc: hx711: update Kconfig, module description and file header

Update the Kconfig entry to "AVIA HX711 and compatible ADCs" and list
supported chips one per line to make it easy to extend when new variants
are added. Change the module description and file header to match.

Add direct includes for linux/array_size.h and linux/types.h rather than
relying on transitive includes pulled in by other headers.

Changes in v4:
- New patch. Split out from the v3 refactor patch as requested by
Andy Shevchenko so that text/description changes are separate from
code refactoring.
- Add direct linux/array_size.h and linux/types.h includes.

- If you say yes here you get support for AVIA HX711 ADC which is used
- for weigh cells
+ If you say Y here you get support for the following AVIA ADCs:
+ - HX711
+ which are used for bridge sensors such as weigh cells.

This driver uses two GPIOs, one acts as the clock and controls the
channel selection and gain, the other one is used for the measurement
