This series adds power management for the hdc3020 humidity and
temperature sensor as well as control over the reset signal the device
provides.

The hdc3020 carries out measurements automatically, which is not
necessary in low-power modes. Furthermore, if the low-power
configuration turns off the device, proper initialization is required to
account for the setup times and initial status register value.

This device provides an active low reset signal that must be handled if
connected. This signal can be used by the driver to keep the device
under minimal power consumption during low-power modes if the power
supply stays active.

This series requires the last additions to the driver to handle events
[1] as well as the fix to include the entries in the Makefile and
Kconfig files [2]. There is still no branch where everything is
included. Therefore, iio/testing has been used as basis and the fix has
been added to the series as it has been applied to iio/fixes-togreg to
make code testing and validation possible.
