[PATCH 4/6] iio: imu: inv_icm42600: Simplify pm_runtime setup

[Sean Nyekjaer]

Remove unnecessary pm_runtime_get_noresume() and pm_runtime_put()
calls during probe. These are not required when the device is marked
active via pm_runtime_set_active() before enabling pm_runtime with
pm_runtime_enable().

Also remove the redundant pm_runtime_put_sync() call from the cleanup
path, since the core is not incrementing the usage count beforehand.

This simplifies the PM setup and avoids manipulating the usage counter
unnecessarily.
