pinctrl: zte: fix leaked of_node references
The call to of_parse_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
Detected by coccinelle with the following warnings:
./drivers/pinctrl/zte/pinctrl-zx.c:415:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 407, but without a corresponding object release within this function.
