usb: hub: delay hub autosuspend if USB3 port is still link training
When initializing a hub we want to give a USB3 port in link training the same debounce delay time before autosuspening the hub as already trained, connected enabled ports. USB3 ports won't reach the enabled state with "current connect status" and "connect status change" bits set until the USB3 link training finishes. Catching the port in link training (polling) and adding the debounce delay prevents unnecessary failed attempts to autosuspend the hub.
