H A Dmax44009.c6aef699a7d7e53164eaac54da57012c8440f1485 Thu Jan 31 09:29:01 CST 2019 Robert Eshleman <bobbyeshleman@gmail.com> iio: light: add driver for MAX44009

The MAX44009 is a low-power ambient light sensor from Maxim
Integrated. It differs from the MAX44000 in that it doesn't have
proximity sensing and that it requires far less current (1 micro-amp
vs 5 micro-amps). The register mapping and feature set between the
two are different enough to require a new driver for the MAX44009.

Developed and tested with a BeagleBone Black and UDOO Neo (i.MX6SX)

Supported features:

* Reading lux (processed value)

* Rising and falling illuminance threshold
events

* Configuring integration time
