[PATCH v4 6/8] iio: adc: ti-ads1015: Convert to managed resources

Use managed resource helpers for the mutex and runtime PM setup.

Replace mutex_init() with devm_mutex_init() and replace the separate
pm_runtime_set_active() and devm_pm_runtime_enable() calls with
devm_pm_runtime_set_active_enabled().

This simplifies resource management and ensures resources are
automatically cleaned up on probe failure and device removal.
