Subject: [PATCH] iio: imu: inv_mpu: Move exports to IIO_MPU6050 namespace
As these exports are only relevant to core module and users in the
bus specific modules, move them out of the main kernel namespace.
Includes using EXPORT_NS_GPL_DEV_PM_OPS() and the simplifications that
brings by allowing the compiler to remove unused struct dev_pm_ops
and callbacks without needing explicit __maybe_unused markings.

Dropped Linus' tag as the new patch is significantly different.
v2: Switch to more flexible version of EXPORT* macro from Paul.
