usb: gadget: composite: Add usb_remove_config

This allows composite drivers to dynamically change their configuration.
For example, a driver might remove a configuration and register a new
one with a different set of functions.
User should prevent the host from enumerating the device while changing
the configuration:

	usb_gadget_disconnect(cdev->gadget);
	usb_remove_config(cdev, old_config);
	usb_add_config(cdev, new_config, new_conf_bind);
	usb_gadget_connect(cdev->gadget);
