usb: ci_udc: Add function to remove usb device
When unregister gadget driver in ci_udc, the usb device is not
removed or stop. This causes next "usb start" fails to work.
Add a new interface "usb_remove_ehci_gadget" in usb-uclass to
remove the usb device for DM driver. Using "usb_lowlevel_stop" for
non-DM driver.
