phy: ti-pipe3: fix device leak at unbind
commit e19bcea99749ce8e8f1d359f68ae03210694ad56 upstream.
Make sure to drop the reference to the control device taken by
of_find_device_by_node() during probe when the driver is unbound.
Fixes: 918ee0d21ba4 ("usb: phy: omap-usb3: Don't use omap_get_control_dev()")
