usb: ohci-nxp: Fix refcount leak in ohci_hcd_nxp_probe

Browse Source 
[ Upstream commit 302970b4cad3ebfda2c05ce06c322ccdc447d17e ]

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