Subject: [PATCH v3 2/5] iio: imu: inv_icm42600: Drop redundant pm_runtime
 reinitialization in resume

Remove unnecessary calls to pm_runtime_disable(), pm_runtime_set_active(),
and pm_runtime_enable() from the resume path. These operations are not
required here and can interfere with proper pm_runtime state handling,
especially when resuming from a pm_runtime suspended state.

Fixes: 31c24c1e93c3 ("iio: imu: inv_icm42600: add core of new inv_icm42600 driver")
