drivers: gpio: siwx91x: Implement device runtime PM for GPIO ports
The existing device runtime PM model requires applications to call
pm_device_runtime_get()/put() on the GPIO controller device directly,
which is not ideal when GPIO ports are exposed as child nodes.
This update enables runtime PM at the GPIO port (child node) level,
allowing applications to manage power through the port devices instead
of the top-level controller.
