Add a specific usb gadget binding test which check that binding a driver without compatible string is working as expected.
the command "bind /usb@1 usb_ether" should give the following "dm tree" command output:
[...] usb 0 [ ] usb_sandbox |-- usb@1 usb_hub 0 [ ] usb_hub | |-- hub usb_emul 0 [ ] usb_sandbox_hub | | `-- hub-emul usb_emul 1 [ ] usb_sandbox_flash | | |-- flash-stick@0 usb_emul 2 [ ] usb_sandbox_flash | | |-- flash-stick@1 usb_emul 3 [ ] usb_sandbox_flash | | |-- flash-stick@2 usb_emul 4 [ ] usb_sandbox_keyb | | `-- keyb@3 eth 4 [ ] usb_ether | `-- usb@1 [...]
