[PATCH 5.4.y] pmdomain: imx: Fix reference count leak in imx_gpc_remove

[Sasha Levin <sashal@kernel.org>]

From: Miaoqian Lin <linmq006@gmail.com>

[ Upstream commit bbde14682eba21d86f5f3d6fe2d371b1f97f1e61 ]

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.

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