USB: sl811: remove CONFIG_USB_DEBUG dependency
This removes the dependency of the driver on CONFIG_USB_DEBUG and moves it to us the dynamic debug subsystem instead. Bonus is the fact that we can now properly determine the exact hardware that is spitting out the messages. This lets debugging be enabled without having to rebuild the driver, an important thing for users that can not do it.
