xhci: move bus_state structure under the xhci_hub structure.
Move the bus_state structure under struct usb_hub.
We need a bus_state strucure for each roothub to keep track of suspend
related info for each port.
Instead of keeping an array of two bus_state structures right under
struct xhci, it makes more sense move them to the xhci_hub structure.
No functional changes.
