Linus Walleij 9a9a369d61 iio: accel: kxsd9: Deploy system and runtime PM 
This deploys runtime and system PM in the KXSD9 driver:

- Use the force_runtime_suspend/resume callbacks as system PM
  operations.

- Add buffer prepare/unprepare callbacks to grab the runtime
  PM while we're using buffered reads and put get/put_autosuspend
  in these.

- Insert get/put_autosuspend calls anywhere the IO is used from
  the raw read/write callbacks.

- Move the fullscale setting to be cached in the state container
  so we can restore it properly when coming back from
  system/runtime suspend.

- Set the autosuspend delay to two orders of magnitude that of
  the sensor start-up time (20ms) so we will autosuspend after
  2s.

- Register the callbacks in both the SPI and I2C subdrivers.

Tested with the I2C KXSD9 on the Qualcomm APQ8060 Dragonboard.
