[PATCH] PCI: imx: fix device node reference leak in imx_pcie_probe

[Miaoqian Lin]

As the doc of of_parse_phandle() states:
"The device_node pointer with refcount incremented.  Use
 * of_node_put() on it when done."
Add missing of_node_put() after of_parse_phandle() call to properly
release the device node reference.

Found via static analysis.
