PCI: imx6: Fix device node reference leak in imx_pcie_probe()

Browse source

In imx_pcie_probe(), of_parse_phandle() returns the device node pointer
with increased refcount. The pointer reference must be dropped by the
caller when it's no longer needed. However, imx_pcie_probe() doesn't drop
the reference, causing reference leak.

Fix this by using the __free(device_node) cleanup handler to drop the
reference when the function goes out of scope.
