thermal/drivers/imx_sc_thermal: Fix refcount leak in imx_sc_thermal_probe

Browse Source 
[ Upstream commit 09700c504d8e63faffd2a2235074e8c5d130cb8f ]

of_find_node_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Fixes: e20db70dba ("thermal: imx_sc: add i.MX system controller thermal support")
