pmdomain: imx: Fix reference count leak in imx_gpc_probe()

Browse source

commit 73cb5f6eaf upstream.

of_get_child_by_name() returns a node pointer with refcount incremented.
Use the __free() attribute to manage the pgc_node reference, ensuring
automatic of_node_put() cleanup when pgc_node goes out of scope.

This eliminates the need for explicit error handling paths and avoids
reference count leaks.
