[USBEHCI_NEW]

- Set the NakCountReload to 0 in the QueueHead that is set in the Async register, as this is a dead QueueHead marked as halted and does not need it.
- Set the Async register in StartController. Note: The Async and Periodic registers can only be modified when the controller is stopped. 
- Driver now works in Qemu.
