pinctrl: mediatek: Fix missing of_node_put() in mtk_pctrl_init
[ Upstream commit dab4df9ca919f59e5b9dd84385eaf34d4f20dbb0 ]
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
Fixes: a6df410d420a ("pinctrl: mediatek: Add Pinctrl/GPIO driver for mt8135.")
