Currently gadget drivers, which do, allocate resources for functions during configuration bind, and free them during function unbind. Which isn't very correct, even though it works for now. Provide a hook in 'struct usb_configuration' as a way for configurations to save pointer to resources allocated during 'bind', which might come handy during 'unbind'.
