[PATCH] soc: imx: gpc: fix reference count leak in imx_gpc_remove

[Miaoqian Lin]

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

Fixes: 721cabf6c660 ("soc: imx: move PGC handling to a new GPC driver")
