pmdomain: imx: scu-pd: Fix device_node reference leak during ->probe()

[ Upstream commit c8e9b6a ]

When calling of_parse_phandle_with_args(), the caller is responsible
to call of_node_put() to release the reference of device node.
In imx_sc_pd_get_console_rsrc(), it does not release the reference.
