[PATCH] pinctrl: rockchip: Fix refcount leak in rockchip_pinctrl_parse_groups

[Miaoqian Lin <linmq006@xxxxxxxxx>]

of_find_node_by_phandle() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.

Fixes: d3e5116119bd ("pinctrl: add pinctrl driver for Rockchip SoCs")
