usb: hub: Add a new API to test if a hub device is root hub
Sometimes we need know if a given hub device is root hub or not.
Add a new API to test this. This removes the xHCI driver's own
version is_root_hub() and change to use the new API.
While we are here, remove the unused/commented out get_usb_device()
in the xHCI driver too.
