pinctrl: mediatek: Fix missing of_node_put() in mtk_pctrl_init

Browse source 
[ Upstream commit dab4df9ca9 ]

The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.

Fixes: a6df410d42 ("pinctrl: mediatek: Add Pinctrl/GPIO driver for mt8135.")
