MFp4: //depot/projects/usb@155834

	Factor out roothub process into the USB bus structure for
	all USB controller drivers. Essentially I am trying to
	save some processes on the root HUB and get away
	from the config thread pradigm. There will be a follow up
	commit where the root HUB control and interrupt callback
	will be moved over to run from the roothub process.
	Total win: 3 processes become 1 for every USB controller.
