usbcore: remove usb_suspend_root_hub
This patch (as740) removes the existing support for autosuspend of root hubs. That support fit in rather awkwardly with the rest of usbcore and it was used only by ohci-hcd. It won't be needed any more since the hub driver will take care of autosuspending all hubs, root or external.

- * usb_hcd_suspend_root_hub - HCD autosuspends downstream ports
- * @hcd: host controller for this root hub
- *
- * This call arranges that usb_hcd_resume_root_hub() is safe to call later;
- * that the HCD's root hub polling is deactivated; and that the root's hub
- * driver is suspended. HCDs may call this to autosuspend when their root
- * hub's downstream ports are all inactive: unpowered, disconnected,
- * disabled, or suspended.
- *
- * The HCD will autoresume on device connect change detection (using SRP
- * or a D+/D- pullup). The HCD also autoresumes on remote wakeup signaling
- * from any ports that are suspended (if that is enabled). In most cases,
- * overcurrent signaling (on powered ports) will also start autoresume.
- *
- * Always called with IRQs blocked.
