usb: host: Fix refcount leak in ehci_hcd_ppc_of_probe

Browse Source 
[ Upstream commit b5c5b13cb45e2c88181308186b0001992cb41954 ]

of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
