Subject: [RFC PATCH 0/2] Introduce PM runtime helper functions

Working on a new driver I noticed that there is a fair amount of duplicate
code for adding PM runtime support.

First patch refactors the PM runtime support in a new header
 <linux/iio/pm_runtime> introducing functions for setup/cleanup and
set power state.

Second patch modifies the KXCJK-1013 driver to use the newly created API. If
this is ok follow up patches will modify the rest of the drivers.

There is a small difference for hid-sensors where the setup sequence additionally
calls pm_suspend_ignore_children. This is taken care of by introducing a 3rd
parameter to iio_pm_runtime_setup.
