[ Upstream commit 89388f8730699c259f8090ec435fb43569efe4ac ]

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

Fixes: 1e747e59cc4d ("pinctrl: rockchip: base regmap supplied by a syscon")
Fixes: 14dee8677e19 ("pinctrl: rockchip: let pmu registers be supplied by a syscon")
