Currently, pm_runtime_resume_and_get() is invoked in the driver's open callback, and pm_runtime_put_autosuspend() is called in the close callback. As a result, the device remains active whenever an application opens it, even if no I/O is performed, leading to unnecessary power consumption. Move the runtime PM calls to the AIE2 callbacks that actually interact with the hardware. The device will automatically suspend after 5 seconds of inactivity (no hardware accesses and no pending commands), and it will be resumed on the next hardware access.
