Jonathan Cameron 687c8848c6 iio: accel: fxls8962af: Use new EXPORT_NS_GPL_DEV_PM_OPS()
Using this macro allows the compiler to remove unused
structures and callbacks if we are not building with
CONFIG_PM* without needing __maybe_unused markings.

Switched to Paul Cercueil's more flexible implementation fo the macro.
Dropped Sean's Ack given new form of macro being used.
