commit 092f45b13e51666fe8ecbf2d6cd247aa7e6c1f74 upstream.
Drivers are not unbound from the device when ulpi_unregister_interface
is called. Move of_node-freeing code to ulpi_dev_release which is called
only after all users are gone.
Fixes: ef6a7bcfb01c ("usb: ulpi: Support device discovery via DT")
