pmdomain: imx: Fix reference count leak in imx_gpc_remove

commit bbde14682eba21d86f5f3d6fe2d371b1f97f1e61 upstream.

of_get_child_by_name() returns a node pointer with refcount incremented, we
should use of_node_put() on it when not needed anymore. Add the missing
of_node_put() to avoid refcount leak.
