[U-Boot] [PATCH v4 3/5] usb: musb: fill in usb_gadget_unregister_driver

[Rob Herring <robherring2@gmail.com>]

From: Rob Herring <robh@kernel.org>

Add missing missing disconnect and unbind calls to the musb gadget driver's
usb_gadget_unregister_driver function. Otherwise, any gadget drivers fail
to uninitialize and run a 2nd time.
