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

[Piyush Patle <piyushpatle228@gmail.com>]

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.
