[PATCH v2 2/4] iio: accel: kxcjk-1013: only set power state if CONFIG_PM is defined

From: Irina Tirdea
Date: Wed Dec 10 2014 - 10:58:23 EST

When CONFIG_PM is not defined and the driver tries to power off the device,
kxcjk1013_set_power_state will call pm_runtime_put_autosuspend, which is
not implemented (wil return -ENOSYS).

Only call pm_runtime calls to change power state when CONFIG_PM is defined.
