Subject: [PATCH] phy: ti: omap-usb2: Fix refcount leak in omap_usb2_probe

of_parse_phandle() 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.

Fixes: 478b6c7436c2 ("usb: phy: omap-usb2: Don't use omap_get_control_dev()")
